· Na1 Ta1 O3

Sodium tantalate (NaTaO₃) is a perovskite-structured ceramic semiconductor combining alkaline and refractory metal oxides. This compound is primarily investigated in photocatalysis and energy conversion research, where its band structure makes it suitable for water splitting and pollutant degradation under UV and visible light; it remains largely a research material rather than a commodity, but represents a promising alternative to established photocatalysts like TiO₂ because of its tunable optical properties and potential for tandem photocatalytic 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.
