· LuTaO3

Lutetium tantalate (LuTaO₃) is a rare-earth perovskite ceramic compound combining lutetium oxide with tantalum pentoxide, typically investigated for high-performance electronic and optical applications. This material belongs to the rare-earth tantalate family and is primarily explored in research and specialized industrial contexts for its potential in high-temperature stability, dielectric properties, and optical transparency in the infrared region. LuTaO₃ is notable for applications requiring combined chemical stability and functional properties at elevated temperatures, positioning it as an alternative to more conventional perovskites in niche high-tech sectors.

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.
