· CsTaO3

CsTaO3 is a perovskite ceramic compound composed of cesium, tantalum, and oxygen, belonging to the class of complex oxide semiconductors. This material is primarily investigated in research settings for photocatalytic and optoelectronic applications, particularly in visible-light-driven photocatalysis and as a potential component in advanced electronic devices. Its perovskite structure and tunable bandgap make it attractive for environmental remediation (water splitting, pollutant degradation) and next-generation semiconductor technologies, though it remains largely experimental compared to more established perovskites like TiO2 or halide perovskites.

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.
