· JVASP-23781· CeReB4

CeReB₄ is a cerium-rhenium boride ceramic compound belonging to the hexaboride family of refractory materials. This is a research-grade ceramic of interest for high-temperature structural applications where exceptional hardness and thermal stability are required. The material combines the refractory properties of rhenium borides with cerium's contribution to density and potential wear resistance, making it a candidate for extreme-environment engineering contexts where conventional ceramics 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.
