ceramic

· JVASP-140179· UB4Ru

UB4Ru is a ceramic compound in the boron-ruthenium system, likely a ruthenium tetraboride or related refractory ceramic. This material belongs to the class of transition metal borides, which are investigated for extreme-temperature and wear-resistant applications due to their exceptional hardness and thermal stability. UB4Ru appears to be a research or specialized composition rather than a widely commercialized engineering ceramic, making it relevant for advanced applications where conventional refractories or ceramics reach their limits.

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.
