· JVASP-114174· Ca3O

Ca₃O is a calcium oxide ceramic compound with a calcium-rich stoichiometry that falls within the family of alkaline earth oxides. This material is primarily of research interest rather than established commercial use, as it represents an understudied composition in the calcium-oxygen phase diagram; most industrial applications focus on conventional calcium oxide (CaO) or calcium hydroxide instead. Engineers considering Ca₃O would be evaluating it for specialized applications in high-temperature ceramics, refractory systems, or advanced material research where its unique crystal structure and thermal properties might offer advantages over standard lime-based compounds.

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.
