· LaAlO3

Lanthanum aluminate (LaAlO3) is a perovskite-structured oxide ceramic known for its high hardness, refractory properties, and excellent chemical stability at elevated temperatures. It is primarily used in advanced electronics and photonics applications, particularly as a substrate material for thin-film deposition and in optical devices, as well as in high-temperature structural applications where chemical inertness and thermal stability are critical; its 2D electron gas properties at heterointerfaces with SrTiO3 have made it especially valuable in emerging condensed-matter physics research and next-generation electronic devices.

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.
