Calcium Silicide (CaSi₂) is an inorganic compound composed of calcium and silicon. It appears as a gray or black solid with a melting point of approximately 1,033°C. This material is insoluble in water but reacts with moisture, producing hydrogen gas and calcium hydroxide. Calcium Silicide is widely used in metal alloy production, pyrotechnics, and deoxidizing agents due to its high reactivity and stability.
Product Overview
Calcium silicide (CaSi₂) is a compound made of calcium and silicon, with the molecular formula CaSi₂. It is highly stable at high temperatures and is commonly used in the production of metal alloys. Calcium silicide is a gray-black solid with a high melting point of 1033°C. It is chemically reactive, decomposing in hot water and easily combusting in air due to the formation of silane.
