· ErCoO3

ErCoO3 is a rare-earth cobalt oxide perovskite compound that functions as a semiconductor material. This ceramic compound combines erbium and cobalt in a perovskite crystal structure, positioning it primarily as a research and development material rather than a mature commercial product. ErCoO3 and related rare-earth cobaltites are investigated for applications requiring mixed ionic-electronic conductivity, catalytic activity, or magnetic properties, particularly in energy conversion and environmental remediation contexts where the unique electronic structure of rare-earth dopants provides advantages over conventional alternatives.

Export Control

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.
