(May 2, 2026) The domestic inorganic silicon materials field has ushered in another major technological breakthrough, and the core preparation process of nano-modified silica and high-purity fumed silica has successfully achieved independent localization and mass production, breaking the long-term technology monopoly of overseas enterprises and laying a solid foundation for the security of supply chains in high-end fields such as coatings, silicones, electronic packaging, and biomedicine in China.

For a long time, the core technology of ultra-high-purity and nano-scale functional silica has been controlled by overseas giants, and high-end products are highly dependent on imports, not only high procurement costs, but also the risk of supply chain supply interruption. Domestic scientific research institutions and leading silicon material enterprises have jointly tackled key key process problems such as ultra-fine particle size control, surface hydrophobic modification, low impurity purification, and continuous vapor synthesis.

After the implementation of this technology iteration, domestic modified silica has reached the international level of similar products in key indicators such as dispersion, reinforcement, weather resistance, and thixotropy, and can completely replace imported products in high-end scenarios such as high-end industrial coatings, liquid silicone rubber, precision electronic seals, and food and pharmaceutical anti-caking agents.

Technological breakthroughs have also led to changes in the industry's production model, from simply imitating and following the trend in the past to a new model of deep integration of industry, education and research, and customized formula research and development. Small and medium-sized manufacturers rely on low-price involution to continue to compress the living space, and enterprises with core patents and process research and development capabilities stand firmly in the high-end market with high value-added products.

Industry experts said that with the continuous maturity of the core technology of domestic silica, large-scale mass production and market popularization will be accelerated in the future, on the one hand, it will greatly reduce the raw material procurement cost of downstream enterprises, and on the other hand, it will help China's silicon-based new material industry chain to move towards high-end, independent and high value-added at full speed.
