Descrizione

Descrizione generale

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.
