CaSi2 Silicon And Calcium Powder For Metallurgical Industry
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.
The main components of calcium silicon are calcium (Ca) and silicon (Si). Calcium is a reactive, silvery-white alkaline earth metal, while silicon is a non-metallic element with a grayish color. When combined, calcium and silicon form a compound known as calcium silicide (CaSi2). The composition of calcium silicon can vary depending on the specific requirements of its application, but it typically contains around 30-35% calcium and 55-65% silicon.
Calcium Silicon 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.
Apart from its use in steelmaking, calcium silicon is also utilized in the production of other alloys, including aluminum alloys, as well as in the manufacturing of certain types of batteries. It is a versatile material that plays a crucial role in various industries where the modification and refinement of metals are required.

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.
Desulfurizer: Calcium silicon reacts with sulfur in the steel, reducing the sulfur content. It helps control the level of sulfur, which can negatively affect the steel's quality and 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.
Packaging:Dark gray luster, 10-100mm granularity, polyethylene plastic bags, net weight of 1000KG per bag, gross weight of 1003KG per bag.
