LaY3
ceramic· JVASP-109977· LaY3
LaY₃ is a lanthanum yttrium oxide ceramic compound belonging to the rare-earth oxide family, valued for its high thermal stability and optical transparency in the infrared spectrum. It is primarily used in specialized thermal and optical applications, particularly in high-temperature furnace windows, infrared optics, and advanced thermal barrier coating systems where conventional ceramics would fail. LaY₃ is notable for combining excellent thermal shock resistance with chemical inertness, making it preferred over alumina or zirconia in demanding environments requiring both thermal performance and optical clarity at elevated temperatures.

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.
