· LaScO3

Lanthanum scandium oxide (LaScO3) is a rare-earth perovskite ceramic compound that combines lanthanum and scandium oxides into a crystalline structure. This material is primarily of research and specialized industrial interest, valued in high-temperature applications where thermal stability and ionic conductivity are critical, particularly in solid oxide fuel cells (SOFCs) and electrolyte membranes. LaScO3 offers potential advantages over conventional ceramics in demanding environments due to its rare-earth composition, which can enhance chemical stability and oxygen ion transport—making it a candidate material for next-generation energy conversion and thermal barrier systems.

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.
