LaCoO3
ceramic· LaCoO3
LaCoO3 is a perovskite-structured ceramic oxide compound combining lanthanum and cobalt, characterized by mixed valence cobalt cations that enable electronic and ionic conductivity. This material is primarily investigated for electrochemical applications where its catalytic activity and oxygen-deficient structure provide advantages in energy conversion and chemical sensing, with notable use in solid oxide fuel cells (SOFCs), oxygen permeation membranes, and catalytic converters where thermal stability and redox cycling tolerance are critical.

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.
