Introduction

Silicon metal slag (also called silicon metal dross or silicon metal scrap) is a by-product in the production of high-purity silicon metal. The surface of molten silicon is covered with slag containing Fe, Al, Ca and other impurities, and silicon slag products with different silicon contents are generated through the density separator.

Silicon metal slag can be used as a deoxidizer to replace ferrosilicon in steelmaking and cast iron production, increasing the fluidity of molten iron, high slagging efficiency, increasing furnace temperature, reducing fuel consumption, improving the toughness and cutting performance of castings, reducing overall production costs and improving productivity.

As a silicon slag supplier, we can supply huge range of silicon slag with different price.

Application

  1. Similar to silicon metal, silicon slag is used as a deoxidizer for steel making.
  2. Used as a deoxidizer for magnesium, chromium and other non-ferrous metals.
  3. Low-cost production of low-grade Si3N4 as a raw material for refractory materials.
  4. Economical raw material for producing silica sol or colloidal silica.
  5. Low-cost raw materials for the production of organosilyl derivatives and silicone products.
