Descripción general
Calcium carbide (CaC2), also referred to as calcium acetylide, is an ionic compound. Technical grade CaC2 is a grey solid with a granular form. The material is reactive with water and forms acetylene gas and calcium hydroxide. Our technical grade material consists of ≥75% CaC2 with the remainder of the composition being calcium oxide, phosphides, sulfides, and nitrides. CaC2 is extensively utilized in the production of acetylene and calcium cyanamide. Additionally, it has been explored in producing phase change materials and as a shape-stabilized phase change material for the efficient utilization of solar energy. Furthermore, it is being investigated as an electrode material for rechargeable calcium batteries.
