· JVASP-98193· ErB4Rh4

ErB4Rh4 is an intermetallic ceramic compound combining erbium boride with rhodium, belonging to the family of rare-earth boride ceramics. This is primarily a research material under investigation for high-temperature structural applications, where the combination of rare-earth and transition-metal elements offers potential for enhanced thermal stability and hardness. The material's development is driven by interest in advanced refractory ceramics for aerospace and extreme-environment engineering, though commercial deployment remains limited compared to established boride and carbide systems.

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.
