ceramic· JVASP-49178· Ca2Ta2O7
Calcium tantalate (Ca₂Ta₂O₇) is a ceramic compound belonging to the family of refractory oxides, characterized by high melting points and chemical stability. This material is primarily of research and advanced applications interest, used in specialized contexts such as high-temperature structural components, thermal barrier coatings, and electronic ceramics where its thermal and chemical resistance provide advantages over conventional oxides. Its tantalum content makes it notably stable in extreme environments, though its cost and processing complexity limit adoption compared to more common ceramic alternatives like alumina or 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.
