· ErC2

ErC2 is a refractory ceramic compound from the rare-earth carbide family, where erbium combines with carbon in a dicarbide crystal structure. This material is primarily of research and specialized industrial interest, valued for its extreme hardness and high-temperature stability in demanding environments. ErC2 finds application in cutting tool coatings, wear-resistant components, and high-temperature structural applications where thermal cycling and mechanical wear are critical concerns.

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.
