· JVASP-141390· Tm4MgS7

Tm4MgS7 is a thulium-magnesium sulfide ceramic compound belonging to the rare-earth sulfide family. This material is primarily of research and developmental interest rather than established in high-volume industrial production, with potential applications in optoelectronics, solid-state lighting, and thermal management systems where rare-earth sulfide ceramics offer unique luminescent or thermal properties. The inclusion of thulium—a lanthanide element—suggests this compound may exhibit specialized optical characteristics or high-temperature stability relevant to advanced ceramic applications.

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.
