High temperature reduction method: Mix silica with a silicon dioxide content of about 95% with coke, and carry out reduction reaction at about 1900℃ to obtain metal silicon with a purity of 97% - 98%. Further purification can obtain metal silicon powder with higher purity.
Metallurgical method: Obtained by smelting silicon ore.
Chemical vapor deposition method: Silicon powder is formed by direct deposition on the substrate through chemical gas reaction.
Ball milling method, roller milling method, and gyratory method: Use silicon blocks as raw materials to produce metal silicon powder using these methods.
