· JVASP-98509· La2SiO5

Lanthanum silicate (La₂SiO₅) is an oxide ceramic compound belonging to the rare-earth silicate family, valued for its thermal and chemical stability at elevated temperatures. This material is primarily used in high-temperature aerospace and industrial applications, including thermal barrier coatings for gas turbine engines and furnace linings, where its low thermal conductivity and resistance to thermal shock provide advantages over conventional zirconia-based systems. La₂SiO₅ is also investigated for nuclear fuel cladding applications and advanced refractory systems due to its crystalline stability and resistance to molten salt and slag corrosion.

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.
