ceramic

· JVASP-36751· LaAuO2

LaAuO2 is a lanthanum gold oxide ceramic compound combining rare-earth and precious-metal elements in an oxide matrix. This is a research-phase material studied primarily for catalytic and electronic applications rather than a commercial engineering ceramic; the lanthanum-gold oxide family is explored for oxidation catalysis, oxygen reduction reactions, and potentially as electrolyte or electrode materials in advanced energy devices.

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.
