· JVASP-116728· Ho2MgS4

Ho₂MgS₄ is a ternary ceramic compound combining holmium, magnesium, and sulfur—representing an uncommon mixed-metal sulfide in the broader family of chalcogenide ceramics. This material is primarily of research and development interest rather than established production use, with potential applications in solid-state ionic conductors, optical materials, or high-temperature ceramic composites where rare-earth sulfide phases offer unique electronic or thermal properties.

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.
