CaTaO2N
semiconductor· CaTaO2N
Calcium tantalum oxynitride (CaTaO₂N) is an inorganic ceramic compound belonging to the perovskite-related oxynitride family, combining metallic (Ca, Ta) and nonmetallic (O, N) elements in a structured lattice. This is a research-phase material primarily investigated for photocatalytic and optoelectronic applications where the band gap engineering enabled by nitrogen incorporation offers improved light absorption compared to pure oxides. CaTaO₂N remains experimental with potential in solar energy conversion, environmental remediation, and visible-light photocatalysis, where its mixed-anion composition provides advantages over conventional tantalate ceramics for next-generation sustainable technologies.

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.
