HoBr3
ceramic· JVASP-33867· HoBr3
HoBr₃ (holmium tribromide) is an inorganic ceramic compound belonging to the rare-earth halide family, composed of the lanthanide element holmium combined with bromine. This material is primarily of research and specialized industrial interest rather than a commodity engineering ceramic, with applications leveraging holmium's unique optical and magnetic properties in controlled chemical environments. It appears in advanced optics, laser systems, and magnetic applications where rare-earth halides offer advantages in transparency, thermal stability, or magnetism that conventional oxides cannot match.

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.
