In 2025, silicon dioxide, as a key inorganic material, will continue to trigger technological innovations in fields such as semiconductors, photovoltaics, and high-end manufacturing. Recently, multiple enterprises and research institutions have promoted the performance upgrade and application scenario expansion of this material through patent layout and industrialization breakthroughs.
Photovoltaic field: high-purity synthesis technology achieves domestic substitution
Kaisheng Technology's annual production line of 5000 tons of semiconductor silicon dioxide has entered the trial production stage with materials, and its product purity can reach up to 6N-7N, targeting the market for photovoltaic crucibles and semiconductor wafer level materials. This project simultaneously develops electronic grade silica sol and low emissivity high-purity ultrafine spherical materials, and is expected to generate small batch orders within the year. This breakthrough will alleviate the domestic photovoltaic industry's dependence on imported high-purity quartz sand and reduce the production cost of monocrystalline silicon rods. According to calculations, the local electricity cost is 50% lower than the national average, further strengthening the regional industrial competitiveness.
Flexible display: Ultra thin glass technology breaks through the bending limit
The patent for "Ultra thin Flexible Glass and Its Preparation Method" applied by Shandong Longguang Tianxu Solar Energy Co., Ltd. shows that its product achieves the technical indicators of a maximum bending radius of 2-3 millimeters and a maximum bending frequency of 350000 times by optimizing the ratio of silicon dioxide to aluminum oxide, lithium oxide and other components. The surface compressive stress of this material reaches 916-937 megapascals, and the Vickers hardness is 610-623 megapascals. It can be widely used in fields such as foldable screen phones and wearable devices. At present, the technology has entered the pilot stage and is expected to achieve mass production by 2026.
Functional materials: Expanding industry boundaries through nanoscale applications
Ningbo Qingyong New Materials Technology has obtained a patent for the preparation method of double mesoporous silica nanospheres. By regulating the pore structure, the material's specific surface area and adsorption performance are improved, providing new solutions for catalyst carriers, drug sustained-release, and other fields. Hubei Xianhe New Materials applies nano silica to the adhesive solution of heat transfer paper, and its modified formula increases the transfer rate by 30% and accelerates the drying speed by 20%. It has been tested and recognized by downstream textile printing and dyeing enterprises.
Industrial pattern: Top enterprises accelerate technological iteration
According to the 2024 financial report of Yuanxiang New Materials, its silicon dioxide business accounts for 98.65%, and it continues to deeply cultivate the market for precipitated white carbon black. Shenzhen Zhihe Carbon Silicon Technology relies on supercritical hydrothermal preparation technology to launch photovoltaic grade high-purity silicon dioxide products and has established cooperation with multiple semiconductor companies. Industry analysts point out that with the increasing demand for material performance in emerging fields such as 5G communication and artificial intelligence, the nanoization and functionalization of silica will become the focus of technological competition.
From photovoltaic crucibles to flexible displays, from catalyst carriers to drug sustained-release, silica is reshaping modern industrial systems in diverse forms. With the continuous breakthrough of technological barriers, this ancient material will unleash greater value in strategic emerging industries such as new energy and electronic information.
