Application fields of heavy calcium carbonate.
Calcium silicate and barium are common additives in steel smelting. The silicon and barium can react with the oxygen in the steel to form oxide impurities such as silica, which are often used as deoxidizers.
Silicon-manganese alloy is mainly used as an intermediate material for deoxidizer and alloy in steel production, and it is also the main raw material for the production of medium and low-carbon ferromanganese.
