ceramic

· YTaO4

YTaO4 is an yttrium tantalate ceramic compound belonging to the family of rare-earth transition metal oxides. This material is primarily investigated for high-temperature structural and functional applications where chemical stability and thermal resistance are critical, though it remains largely in the research and development phase rather than established industrial production.

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.
