· JVASP-146217· Ho4US7

Ho4US7 is a ceramic compound containing holmium, uranium, and sulfur in a 4:1:7 stoichiometric ratio. This is a rare-earth ceramic material that appears to be primarily a research or specialized composition rather than a widely commercialized engineering ceramic. The holmium-uranium-sulfur family is of interest in nuclear materials science, refractory applications, and advanced ceramics research where high-temperature stability and unique electronic or magnetic properties may be leveraged.

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.
