(National Tenth Five-Year Plan for tackling key scientific and technological problems), which started from 2002 to 2004.
First, the content introduction
Ultra-fine high-purity quartz powder is used as high-quality silicon raw material in high-tech fields such as optical fiber, microelectronics industry and pure silicon preparation. In the traditional industry, high-purity time is generally prepared from high-quality crystals. With the decrease of high-quality crystal resources and the rapid growth of demand for high-purity timing products, it is becoming more and more urgent and important to prepare high-purity timing products by using pulse timing with abundant resources in China. Through technical cooperation with Russia, the center has solved the problem of domestic dependence on foreign imports of such raw materials, and developed special equipment for processing ultra-fine and high-purity materials.
Second, popularization and application
It has been widely used in Zhejiang Jingpin Material Factory and other units.
