Product Overview of Silicon Metal Powder
Metal silicon powder is processed from metallic silicon, and the purity is usually between 98% and 99%. Zhenan Metallurgy uses advanced crushing and screening processes to process metallic silicon into fine powders of various particle sizes to meet the needs of high reactivity and uniformity in different industrial applications.
Metal silicon powder is a fine powder made of metallic silicon, usually gray or black. The metal silicon is cleaned, selected and ground to make fine powder of 20 mesh to 600 mesh. According to the content, metal silicon powder can be divided into 90% metal silicon powder and 95%, 97%, 98%, 99.99% and other quality standards.
In the production process of refractory materials, metal silicon powder of different specifications can be selected according to the requirements of refractory materials, thereby greatly reducing the cost of refractory materials.
- General grade metal silicon powder (such as 553, 441 grades): The silicon content is usually between 98.5% and 99.0%, and the impurity content of iron, aluminum, calcium, etc. is controlled within a specific range. Suitable for steelmaking, casting and general aluminum alloy production, as a deoxidizer, alloying agent and inoculant to improve material strength, hardness and corrosion resistance.
- High-purity metal silicon powder (such as 3303, 2202, 1101 grades): The silicon content can reach more than 99.0%, and the impurity content of iron, aluminum, calcium and other impurities is significantly reduced (for example, the maximum impurity content of iron, aluminum and calcium in 2202 grade is 0.2%, 0.2% and 0.02% respectively). These grades are the key to the production of high-quality aluminum ingots, refining processes, advanced chemicals and solar-grade silicon.
- Ultra-high purity metal silicon powder (such as 7N grade): Silicon powder with a purity of up to 99.99999% can be provided, which is specially designed for cutting-edge semiconductor manufacturing, advanced electronic components and precision optical applications to meet extremely stringent requirements on impurity content.
