· JVASP-3714· CaH2O2

CaH₂O₂ (calcium hydride oxide) is a ceramic compound containing calcium, hydrogen, and oxygen, representing a mixed-valence or hydride-bearing oxide system that falls outside conventional oxide ceramics. This material is primarily of research interest rather than established industrial use, being studied for potential applications in hydrogen storage, advanced refractory systems, and solid-state chemistry where the hydride component offers unique chemical properties distinct from traditional calcium oxides or hydroxides.

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.
