· JVASP-125381· CaH3

Calcium hydride (CaH₃) is an ionic ceramic compound belonging to the metal hydride family, characterized by calcium cations bonded with hydride anions in a crystalline structure. This material is primarily investigated in research and industrial contexts as a hydrogen storage medium and chemical reducing agent, with potential applications in hydrogen generation systems and as a precursor for synthesizing other calcium compounds. CaH₃ is notable for its capability to react with water or moisture to release hydrogen gas, making it of interest in emerging hydrogen energy technologies, though practical engineering deployment remains limited compared to conventional hydride storage materials.

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.
