ceramic

· JVASP-1825· LiHoS2

LiHoS₂ is a rare-earth lithium sulfide ceramic compound combining lithium, holmium (a lanthanide), and sulfur. This is a research-phase material studied primarily in solid-state chemistry and materials science rather than an established commercial ceramic; it belongs to the sulfide ceramic family and represents exploration into mixed-metal sulfide systems for potential electrochemical or optical 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.
