· JVASP-140814· Ce2Ta2O9

Ce2Ta2O9 is a mixed rare-earth tantalate ceramic compound combining cerium oxide with tantalum pentoxide, belonging to the family of complex oxide ceramics. This material is primarily of research and development interest for high-temperature applications, particularly in thermal barrier coatings and advanced ceramic systems where chemical stability and refractoriness are required. Its notable characteristics include potential resistance to corrosion and thermal cycling, making it relevant where conventional oxides may degrade, though it remains less commercially established than simpler oxide ceramics or stabilized zirconia alternatives.

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.
