· JVASP-56958· HoB2Rh2C

HoB₂Rh₂C is an advanced ceramic compound combining holmium, boron, rhodium, and carbon—a quaternary ceramic that belongs to the rare-earth borocarbide family. This is a research-phase material studied for its potential as an ultra-high-temperature structural ceramic, leveraging the refractory properties of borocarbides and the thermal stability contributions of holmium and rhodium. Such materials are of interest where conventional superalloys reach their limits, though HoB₂Rh₂C remains primarily in exploratory development rather than established production.

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.
