Recently, domestic research teams have made a groundbreaking progress in the field of high-purity silica extraction technology, successfully preparing nano-scale silica materials with a purity of 99.999%. This achievement has broken the long-term technological monopoly of foreign countries in this field, filled the key material gap in domestic related industries, and provided important support for the independent development of China's semiconductor, photovoltaic and other high-tech industries.

As a core raw material in semiconductor manufacturing, photovoltaic industry and other fields, the purity and performance of high-purity silica directly affect the quality of end products. Previously, China's high-purity silica has long relied on imports, especially in high-end application scenarios such as semiconductor packaging and photovoltaic quartz crucibles, foreign enterprises have almost occupied a dominant position in the market, which not only increases the cost of the industrial chain, but also poses potential risks to industrial security. The traditional production of high-purity silica mostly relies on the purification of natural quartz ore, which is limited by resource reserves and purification processes, making it difficult to meet the growing high-end demand.The key to this breakthrough lies in the adoption of innovative gas-phase synthesis technology. Researchers use high-purity silicon materials as raw materials, and through precise control of reaction temperature, gas ratio and other parameters, silicon raw materials undergo chemical reactions in a high-temperature gas-phase environment to directly generate nano-scale silica particles. This technology not only gets rid of the dependence on natural quartz ore, but also can accurately control the purity and particle size distribution of products through process optimization, and the product performance reaches the international advanced level. At the same time, the new process realizes low emission of waste in the production process, which is in line with the development concept of green manufacturing.

The application prospect of this technological achievement is very broad. In the semiconductor field, high-purity silica can be used to manufacture key components such as chip packaging materials and photolithographic masks, improving the stability and performance of chips; in the photovoltaic industry, as the core raw material of quartz crucibles, it can effectively improve the purity and conversion efficiency of silicon wafers; in addition, it can also be applied in optical glass, optical fiber communication and other fields, promoting the technological upgrading of related industries.

With the rapid development of 5G, artificial intelligence, new energy and other industries, the global demand for high-purity silica continues to rise. This technological breakthrough will significantly improve China's self-sufficiency in this material field, reduce external dependence, and enhance the security and resilience of the industrial chain and supply chain. At present, relevant research teams are cooperating with the industry to promote the industrialization of technological achievements, and it is expected that large-scale production capacity will be gradually formed in the next few years, injecting new momentum into the high-quality development of China's high-tech industries.
