CaTaO3
ceramic· CaTaO3
Calcium tantalate (CaTaO3) is a perovskite ceramic compound combining alkaline earth and refractory metal oxides, notable for its high density and stiffness. This material is primarily explored in research contexts for high-temperature applications, photocatalysis, and dielectric devices where tantalum-based ceramics offer chemical stability and thermal resistance. Engineers consider CaTaO3 when conventional oxides prove insufficient in demanding environments, though it remains less established than commercial alternatives like alumina or yttria-stabilized zirconia.

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.
