· JVASP-120274· LaAlO2

Lanthanum aluminate (LaAlO₂) is a ceramic oxide compound combining rare-earth lanthanum with aluminum oxide, belonging to the perovskite-family ceramics widely studied for advanced electronic and optical applications. It is primarily encountered in research and emerging technologies rather than high-volume commercial production, particularly in thin-film electronics, integrated photonics, and as a substrate material for oxide heterostructures. The material is notable for its chemical stability, high refractive index, and wide bandgap, making it attractive for next-generation semiconductor devices, laser applications, and interfaces in novel oxide-based electronics where conventional materials reach performance limits.

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.
