Application of modified silica powder

Crystalline silicon powder is mainly used in large-scale integrated circuit packaging. It is also widely used in aviation, aerospace, fine chemical industry, erasable optical disk, large area electronic substrate, special ceramics and daily cosmetics. Experts predict that by 2010, China's demand for crystalline silicon powder alone will reach 20000-30000 tons, and high-purity silicon powder will reach 100000 tons, with an average annual growth rate of more than 20%. The world's demand for crystalline silicon powder will exceed 300000 tons, worth tens of billions of yuan. With the rapid development of China's microelectronics industry, the requirements of large-scale and ultra large-scale integrated circuits for packaging materials are higher and higher, which not only requires ultra-fine, but also requires high purity, especially for the spherical shape of particles. However, the preparation of crystalline silicon powder is an interdisciplinary and difficult project. At present, only a few countries in the world master this technology, such as the United States, Japan, Germany, Canada and Russia. As we all know, the spherical silicon oxide currently purchased in China mainly comes from Japan and South Korea. The imported spherical silicon oxide has high price and long transportation cycle. The high-quality spherical silica produced in China has the advantage of localization and can completely replace the imported ones.

As a filler in epoxy resin system, it can save a lot of epoxy resin.
