· La0.05Ca2.85Co3.8O8.55

La0.05Ca2.85Co3.8O8.55 is a lanthanum-doped calcium cobalt oxide ceramic compound, a mixed-valence oxide belonging to the family of layered perovskite and Ruddlesden-Popper structures. This material is primarily investigated for electrochemical applications, particularly as a cathode material or oxygen reduction catalyst in solid oxide fuel cells (SOFCs) and oxygen permeation membranes, where its mixed ionic-electronic conductivity and catalytic activity at high temperatures are advantageous. The substitution of lanthanum and compositional tuning of the cobalt oxidation state make it notable for balancing thermal stability, chemical compatibility with electrolytes, and oxygen transport properties compared to conventional cobalt oxide cathodes.

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.
