· JVASP-123211· Er3In

Er₃In is an intermetallic ceramic compound combining erbium (a rare-earth element) with indium, forming a hard ceramic material. This is a research-phase material studied primarily for its potential in high-temperature applications and advanced functional ceramics, as rare-earth intermetallics can exhibit superior thermal stability, oxidation resistance, and electronic properties compared to conventional ceramics. Er₃In and related erbium-indium phases remain largely experimental; their development is driven by aerospace, electronics, and materials science research communities exploring next-generation thermal barrier coatings, semiconductor substrates, and specialized high-temperature structural components.

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.
