ceramic· JVASP-35432· Er2B4C
Er₂B₄C is an erbium-based ceramic compound combining rare-earth, boron, and carbon constituents. This material belongs to the family of rare-earth borocarbides, which are primarily investigated for high-temperature structural applications and specialized functional uses where thermal stability and chemical resistance are critical. While still largely in the research phase, Er₂B₄C and related borocarbides show promise in aerospace and extreme-environment contexts where conventional ceramics face limitations.

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.
