· JVASP-139615· NaTaO

Sodium tantalate (NaTaO₃) is an inorganic ceramic compound combining sodium and tantalum oxides, belonging to the perovskite family of materials. This material is primarily investigated for photocatalytic and photoelectrochemical applications, particularly in water splitting and environmental remediation, where its semiconductor properties and crystal structure enable light-driven chemical reactions. NaTaO₃ is not yet widely deployed in high-volume industrial production but represents a promising research direction in sustainable energy and green chemistry, offering advantages over traditional photocatalysts in specific wavelength utilization and chemical stability.

Regulatory Screening

Environmental

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.
