Our company specializes in the production of silicon metal powder or industrial silicon powder: 1. Production process: Silicon metal or industrial silicon blocks (grades such as 2202, 3303, 441, 553, etc.) are washed, selected, dried, ground, and processed into fine powders of 200 mesh and 320 mesh. Based on content, they can be categorized into various quality standards such as 92%, 95%, 97%, and 98%. 2. Physicochemical indicators: Silicon metal powder is produced by smelting and processing high-quality silicon metal blocks to remove iron. Its physicochemical indicators are as follows: Item Si(%) Ca(%) Fe(%) Fineness Content ≥98 0.30 0.60 200 mesh ≥97 0.35 0.70 200 mesh ≥95 0.50 0.75 200 mesh 3. Applications: Mainly used in silicone chemical products, refractory materials, high-tech ceramics, and powder metallurgy. Silicon content is around 98%, with high-quality products reaching up to 99.8% Si. There are different grades such as 441 and 553. At the same time, we also provide products and services for industries including electronics, optics, building materials, machinery, chemicals, metallurgy, and refractory materials. Among these, silicon metal powder is processed from high-quality industrial silicon and is available in various specifications. It is widely used in aerospace, aviation, metallurgy, electronics, chemistry, refractory materials, and other industries. 4.
