· LaSiO3

Lanthanum silicate (LaSiO₃) is an inorganic ceramic compound composed of lanthanum oxide and silicon dioxide, belonging to the family of rare-earth silicates. It is primarily investigated as a thermal barrier coating (TBC) material and environmental barrier coating (EBC) for high-temperature aerospace applications, particularly as an alternative or complement to yttria-stabilized zirconia in next-generation gas turbines and hypersonic vehicle structures where improved thermal stability and lower sintering rates are desired.

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.
