Calcium silicon, also known as calcium silicide, is an alloy composed of calcium, silicon, and traces of other elements. It is primarily used as a deoxidizer, desulfurizer, and an alloying agent in the steelmaking industry.
In the production of cast iron, calcium silicon is more effective in improving the properties of cast iron than ferrosilicon. Silicon-calcium alloy is not only an effective inoculant to promote the formation of spheroidal graphite, but also has the effects of deoxidation, desulfurization, denitrification and silicon increase.
Function
Calcium and silicon have a strong affinity with oxygen. Especially calcium metal has a strong affinity with oxygen and has a strong affinity with sulfur and nitrogen. Therefore, calcium silicon is an ideal composite deoxidizer and desulfurizer. Silicon alloys have a strong deoxidizing ability, which helps the deoxidized products easily float and discharge, but can also improve steel’s performance in the plasticity, impact toughness, and fluidity,ductility. At present, calcium silicon alloy can replace aluminum for final deoxidation.

Applications
Steelmaking: Calcium silicon is added to molten steel to improve its quality and performance. It serves multiple purposes in the steelmaking process:
Deoxidizer: Calcium silicon reacts with oxygen in the molten steel, reducing the oxygen content and removing impurities. This helps enhance the steel's cleanliness and mechanical properties.
Alloying agent: Calcium silicon serves as an alloying agent by introducing calcium and silicon into the steel. This helps modify the steel's composition and improves its strength, castability, and other desired characteristics.
Aluminum industry: Calcium silicon is also used in aluminum alloys. It helps refine the structure of aluminum and improves its mechanical properties, such as strength and ductility.
Packaging:Dark gray luster, 10-100mm granularity, polyethylene plastic bags, net weight of 1000KG per bag, gross weight of 1003KG per bag.
