ceramic· JVASP-128836· ErAs5
ErAs is a rare-earth arsenide ceramic compound combining erbium (Er) with arsenic (As), belonging to the family of intermetallic and compound semiconductors. While ErAs remains primarily a research material, it is of significant interest in thermoelectric and optoelectronic applications due to its potential for high-temperature operation and thermal transport properties; the material family shows promise for infrared detectors, thermal-to-electric energy conversion, and integrated photonic devices where rare-earth compounds can provide unique band structures unavailable in conventional semiconductors.

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.
