· La0.8Sr0.2CoO3

La₀.₈Sr₀.₂CoO₃ is a perovskite-based mixed oxide ceramic composed of lanthanum, strontium, and cobalt. This material is primarily investigated as a cathode material for solid oxide fuel cells (SOFCs) and oxygen permeation membranes, where it offers improved electrochemical activity and oxygen reduction kinetics compared to conventional cathode materials. The strontium doping enhances electrical conductivity and sintering behavior, making it a candidate for intermediate-temperature fuel cell operation and applications requiring controlled oxygen transport.

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.
