· Ca2 Ta8 O22

Ca₂Ta₈O₂₂ is a complex oxide ceramic compound belonging to the tantalate family, characterized by a mixed-valence structure combining calcium and tantalum oxides. This material is primarily of research and development interest rather than an established commercial product, with potential applications in advanced ceramics where high-temperature stability, electrical properties, and chemical inertness are valued. The tantalate oxide family is explored for semiconducting and ionic-conducting applications in specialized electronic and energy storage devices, where researchers investigate this composition's phase stability and functional properties relative to simpler tantalate systems.

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.
