· JVASP-120069· Ca2TaO3

Calcium tantalate (Ca₂TaO₃) is a dense ceramic compound combining alkaline earth and refractory metal oxides, belonging to the family of complex oxide perovskites and related structures. While primarily investigated in research and development contexts, this material is of interest for high-temperature applications, dielectric devices, and specialized optical or electronic systems where tantalum's refractory properties and high density offer advantages over conventional ceramics. Its potential spans applications requiring thermal stability, chemical inertness, and electrical functionality in demanding environments.

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.
