In 2026, China’s silicon-based new material industry has ushered in a full-cycle high-quality development period. Supported by technological breakthroughs across categories including organosilicon, high-purity silicon wafers, special silanes, functional white carbon black, silicon-carbon anode materials and quantum-grade high-purity silicon isotopes, China’s silicon fine chemical industrial chain has completely bid farewell to the extensive capacity expansion phase and entered a new development stage featuring refined purification, functional modification, high-end application and customized services. Driven powerfully by the national strategy for new material development, dual-carbon green policies and the demand for independent controllability of high-end manufacturing supply chains, coupled with the sustained prosperity of downstream core industries such as new energy, semiconductors, optoelectronic information, high-end equipment and biomedicine, the market scale of silicon-based new materials continues to expand, the industrial structure undergoes in-depth optimization, and the process of domestic substitution for high-end products accelerates in an all-round way, forming a core pillar supporting the transformation and upgrading of domestic fine chemicals and the breakthrough of strategic emerging industries.

　　Looking back on the industrial development, China’s silicon chemical sector has long focused on the large-scale production of basic raw materials. General-grade organosilicon monomers, ordinary precipitated white carbon black, industrial-grade silanes and conventional silicon wafers suffer from overcapacity and fierce homogeneous competition, staying at the low and middle end of the global industrial chain for a long time. These products feature low added value, weak technical barriers and narrow profit margins. The industry used to rely on production capacity and low prices to seize the market, while core high-end materials, precision preparation processes and high-end testing systems were monopolized by overseas leading enterprises. In recent years, with increasingly stringent control over environmental protection and energy consumption and intensified efforts to phase out backward production capacity, a large number of outdated production lines with high energy consumption, heavy pollution, backward processes and low benefits have been phased out at an accelerated pace. Invalid industrial supply keeps shrinking, and industrial resources, capital, technology and talents are rapidly gathered in leading enterprises equipped with green production capacity, core R&D technologies and high-end customized service capabilities. Industrial concentration rises steadily, freeing up sufficient market space and production resources for the industrialization and mass production of high-end new materials.

　　From the perspective of demand in segmented tracks, the explosive growth of multiple downstream sectors continues to lift the ceiling of incremental demand for silicon-based new materials. Breakthroughs have been made in the semiconductor and quantum technology fields. In 2026, China independently achieved mass production of silicon-28 isotopes with an abundance exceeding 99.99%, completely resolving the bottleneck of core materials for silicon-based quantum chips and filling the gap in domestic high-purity silicon material industry. It provides core material support for quantum computing, advanced semiconductor processes, high-precision metrology, aerospace navigation and other cutting-edge fields. Meanwhile, the global silicon wafer market continues to recover. The surging demand for AI computing chips, high-bandwidth storage and automotive power semiconductors keeps the supply of 300mm high-end silicon wafers tight. Domestic wafer production capacity climbs rapidly, bringing incremental demand from both mature and advanced processes.

　　The new energy industry serves as the biggest growth engine for silicon-based materials, with photovoltaic, power battery and new energy vehicle tracks thriving simultaneously. Continuous capacity expansion and iteration in the photovoltaic sector drive rising consumption of high-purity polysilicon, photovoltaic encapsulating silicone, high-dispersion reinforcing white carbon black and weather-resistant modified silicon materials. Green silicon-based materials enable efficient sealing, anti-aging and UV resistance of photovoltaic modules, greatly extending service life and power generation efficiency of photovoltaic equipment. For power batteries, silicon-carbon anode materials have entered the first year of industrial mass production. Boasting ultra-high capacity density, they effectively tackle the pain point of insufficient energy density of traditional graphite anodes and facilitate lightweighting and long-range upgrading of power batteries. In the new energy vehicle sector, high-temperature resistant silicone rubber, insulating organosilicon potting materials and modified white carbon black specially for low rolling resistance tires fully meet the stringent working condition requirements of vehicle three-electric systems, high-voltage wiring harnesses and intelligent chassis, with market demand maintaining rapid growth.

　　Demand upgrading in high-end precision manufacturing and livelihood sectors further broadens the application boundary of materials. The high-end electronic and electrical, optoelectronic display industries have strong demand for ultra-high-purity silane reagents, electronic-grade high-purity white carbon black and low-volatile modified organosilicon. The materials need to meet extreme performance requirements including zero impurities, high insulation, resistance to high and low temperatures, anti-aging and low volatility to guarantee long-term stable operation of precision electronic devices. High-end waterborne coatings, special printing inks, medical devices, personal care, rail transit and other fields keep iterating formulas of high-end functional silicon materials, promoting the batch application of customized silicon-based new materials with hydrophilic, hydrophobic, high-temperature resistant, bacteriostatic and high-adhesion properties. This completely changes the historical limitations of traditional silicon materials such as single application scenarios and constrained performance.

　　In terms of technological R&D and production processes, all-round independent breakthroughs have been achieved in domestic industries. High-end phenyl silicon materials, special copolymer silicone resins, hydrophobically modified powders, high-purity silane coupling agents, quantum-grade high-purity silicon isotopes and other products that once relied heavily on imports now have mature localization technologies. Domestic enterprises, in collaboration with research institutes, keep tackling core technologies including precise powder modification, customized silicon molecular structure design, green catalytic synthesis, ultra-high-purity purification and low-residue refining. They continuously optimize production processes, effectively reducing product impurity content, improving batch stability and enhancing mechanical properties and weather resistance of materials. At the same time, green production technologies have been widely popularized. Mother liquor recycling, silicon resource regeneration and low-carbon synthesis processes have been widely implemented, greatly cutting production energy consumption and pollutant emissions and realizing dual upgrading of environmental benefits and product quality. The performance indicators of domestic high-end silicon-based new materials have fully reached the standards of top international brands, and these products have been supplied in bulk to the supply chains of global high-end customers.

　　The supply and demand landscape of the industry has undergone fundamental reshaping, with structural differentiation becoming increasingly prominent. The market for low-end general silicon-based raw materials remains in stock competition, with prices fluctuating at low levels and profits continuously squeezed. Small and medium-sized manufacturers focusing on low-end products face shrinking living space. In contrast, the market for high-end fine, functionally customized and ultra-high-purity silicon-based new materials is in short supply, with extended order lead times and high gross profit margins, forming the core profit pillar of leading enterprises. The logic of industrial competition has been completely transformed. Instead of competing in production capacity and prices, enterprises now compete in core modification technologies, customized R&D capabilities, batch stability, supporting formula services and green production qualifications. Enterprises that can deeply bind downstream high-end industrial chains, quickly respond to customers’ customized requirements and provide integrated solutions combining materials, process debugging and technical after-sales services keep capturing incremental dividends of the industry.

　　The structure of foreign trade import and export keeps optimizing, and the global competitiveness of domestic silicon-based new materials has been greatly improved. Exports of traditional basic silicon chemical raw materials remain stable, consolidating market share in the global low and middle-end markets with cost advantages. Exports of high value-added modified silicon materials, high-purity silicon reagents, semiconductor-grade silicon wafers and quantum high-purity silicon materials maintain rapid growth. Recognition of domestic silicon-based new materials among overseas high-end markets in Southeast Asia, Europe, the Middle East and North America continues to rise. As the international certification system of domestic products is gradually improved and product performance stability keeps upgrading, the long-standing monopoly of overseas brands in high-end markets is gradually broken. China’s silicon industry has officially transformed from a “major exporter of basic raw materials” to a “powerhouse in exporting high-end new materials”, becoming a core driving force for the upgrading of global fine chemical materials.

　　According to analysis by authoritative industrial institutions, the period from 2026 to 2028 will be the golden upgrading cycle for China’s silicon-based new material industry. Strategic industries including downstream semiconductors, quantum technology, new energy and high-end manufacturing will maintain rapid growth, continuously driving iterative upgrading and capacity expansion of high-end silicon materials. Meanwhile, the continuously tightening domestic regulations on environmental protection, energy consumption and work safety will further phase out backward low-end production capacity and promote continuous optimization of the industrial structure. In the medium and long run, leading enterprises mastering core synthesis and modification technologies, complete product portfolios, green mass production capacity and supporting technical service systems will continue to reap triple dividends from industrial upgrading, domestic substitution and overseas market expansion. In the future, China’s silicon-based new material industry will keep breaking through high-end technical barriers, enrich the matrix of high-end products, and gradually build a modern silicon-based new material industrial system that is independently controllable, safe, efficient and globally leading, helping China’s fine chemical and high-end new material industries achieve leapfrog high-quality development.
