HoB2Ru
ceramic· JVASP-153302· HoB2Ru
HoB2Ru is a ternary ceramic compound combining holmium, boron, and ruthenium—a rare material that belongs to the family of transition metal borides and represents an emerging research composition rather than a widely commercialized engineering ceramic. This compound is of primary interest in materials research for ultra-high-temperature applications and advanced structural ceramics, where the combination of rare-earth and refractory metal elements may offer unique thermal stability, hardness, or oxidation resistance. Its development reflects ongoing efforts to create novel high-entropy and multi-principal-element ceramics for demanding aerospace, defense, and thermal protection 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.
