· JVASP-117957· Ca2C

Calcium carbide (Ca₂C) is an inorganic ceramic compound that forms a hard, crystalline solid at room temperature. It is primarily used as a chemical precursor for acetylene gas production via hydrolysis, and historically as a carbide tool material for cutting and grinding applications in machining. While largely superseded by modern synthetic alternatives in cutting tools, Ca₂C remains relevant in specialized chemical synthesis, legacy industrial processes, and materials research exploring ceramic carbides for refractory and high-temperature applications.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
