· JVASP-119022· ErB4Ir4

ErB4Ir4 is an intermetallic ceramic compound combining erbium, boron, and iridium—a quaternary phase material that belongs to the family of refractory boride ceramics. This is a research-level compound with limited commercial production; it is primarily of interest in materials science studies exploring high-temperature structural ceramics and wear-resistant coatings, where the combination of a rare-earth metal (erbium) with the hardness of borides and the oxidation resistance of iridium offers potential for extreme-environment applications. The material's appeal lies in tailoring ceramic properties for niche aerospace, nuclear, or advanced manufacturing environments where conventional refractory materials fall short.

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.
