Spherical silica powderThe technology uses natural fine quartz minerals as raw materials and adopts low-cost, high-quality technology.

Using a sol-gel process, in the presence of a dispersant and a spherical catalyst, high-purity spherical amorphous silicon is prepared, which is melted into spherical amorphous silicon by flame or ion flame method. In the high-end market, such as integrated circuit packaging, the second process is adopted.

Spherical silicon powder is mainly used in high-tech fields such as large-scale integrated circuits, aerospace, fine chemicals, erasable optical discs, large-area electronic substrates, special ceramics, daily cosmetics, etc. The market is huge. Experts estimate that by 2010, China’s demand for spherical silicon powder will be 20,000 to 30,000 tons, and high-purity silicon powder will be 100,000 tons, with an average annual growth rate of over 20%. The global demand for spherical silica powder will exceed 300,000 tons, worth 10 billion yuan. With the rapid development of China’s microelectronics industry, the requirements for packaging materials for large-scale, high-ultra-large-scale integrated circuits are getting higher and higher. Not only are the requirements for ultra-fine powders higher and higher, but also the requirements for high-purity packaging materials. The higher the coming, especially the higher and higher requirements for spherical particles.

However, the preparation of spherical silica powder is an interdisciplinary and difficult subject. At present, only a few in the world such as the United States, Japan, Germany, Canada and Russia have mastered this technology. As we all know, spherical silica mainly comes from Japan and Korea. Imported spherical silica is expensive and has a long transportation cycle. The high-quality spherical silica produced in China has the advantage of localization and can completely replace imports.
