· JVASP-143656· Ho2ZnS4

Ho₂ZnS₄ is a ternary ceramic compound combining holmium, zinc, and sulfur—a rare-earth-containing chalcogenide belonging to the spinel or related sulfide family. This is primarily a research-phase material studied for its potential optical, magnetic, and electronic properties rather than a widely commercialized engineering ceramic. Interest in this compound centers on applications requiring rare-earth doping or magnetism at the ceramic level, where the holmium dopant can impart magnetic ordering or photoluminescence relevant to photonics and magnetostrictive device research.

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.
