· La0.95Sr0.05CoO3

La0.95Sr0.05CoO3 is a strontium-doped lanthanum cobaltite ceramic oxide belonging to the perovskite family, synthesized primarily for energy conversion and catalytic applications. This material is investigated as a cathode material for solid oxide fuel cells (SOFCs) and as a catalyst support or active phase in oxygen reduction reactions, where partial strontium substitution enhances electrochemical performance compared to undoped lanthanum cobaltite. Engineers select this composition over pure LaCoO3 for its improved ionic and electronic conductivity, making it particularly relevant for high-temperature electrochemical devices operating in the 600–800 °C range.

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.
