Introduction:
Slag material is a byproduct from production of silicon metal of ≥99% purity. To ensure the quality of the silicon metal, top portion of the melt is separated when draining from the electric-arc furnace. The less pure portion of silicon metal typically contains higher contents of iron, aluminum, calcium and other slag. With the employment of density separation machines, different grades of silicon slag are segregated efficiently.
Usage:
The silicon slag is much cheaper than ≥99% purity silicon metal, and has many industrial applications. For example, It is
1. Used as deoxidizing agent in steel production to reduce oxygen levels in the melt via reaction such as Si + 2 O (in liquid Fe) ––> SiO2 (SiO2 is formed as a solid dispersed in molten Fe, and subsequently floats to the surface of the melt. It is removed by either skimming or by draining molten iron from the bottom);
2. Use as deoxidizing agent in the production of magnesium, chromium and other metals via the same mechanism;
3. Used in the production of lower grade of Si3N4 in a cost effective manner, the material is suitable for refractory applications such as refractory bricks and other high-temperature applications;
4. An economical feedstock in the manufacture of silica sol or colloidal silica;
5. A low cost feedstock in the manufacture of organosilyl derivatives and silicone products
