· NaTaO3

Sodium tantalate (NaTaO3) is a perovskite ceramic semiconductor composed of sodium, tantalum, and oxygen. It is primarily investigated in photocatalytic applications, particularly for water splitting and hydrogen generation under UV and visible light irradiation, where its tunable bandgap and crystal structure offer advantages over traditional titania-based photocatalysts. This material remains largely in the research and development phase but shows promise in environmental remediation and renewable energy applications where engineers seek photocatalysts with improved efficiency and stability compared to conventional alternatives.

Export Control

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.
