· JVASP-129889· Ca3S

Calcium sulfide (Ca₃S) is an inorganic ceramic compound belonging to the sulfide family of ceramics, characterized by calcium and sulfur bonding in a crystalline structure. This material is primarily of research and specialized industrial interest, with applications in photoluminescent coatings, phosphor materials for display technologies, and as a precursor in synthesis of other functional ceramics. Ca₃S is notable within the sulfide ceramic family for its potential in optical and luminescent applications where traditional oxides are unsuitable, though it remains less common than calcium sulfate or other calcium compounds in mainstream engineering practice.

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.
