· JVASP-135428· YMgS

YMgS is a rare-earth ceramic compound combining yttrium, magnesium, and sulfur, belonging to the family of mixed-metal sulfide ceramics. This is primarily a research material investigated for its potential in high-temperature structural applications and solid-state ionic conductivity, rather than a mainstream engineering ceramic. The material shows promise in specialized contexts such as solid electrolytes, thermal barriers, and advanced refractory systems where its unique phase stability and composition offer advantages over conventional oxides or single-metal sulfides.

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.
