· NaBiO3

Sodium bismuthate (NaBiO3) is an inorganic ceramic compound and semiconductor material composed of sodium and bismuth oxides. It is primarily investigated in research and emerging applications for photocatalysis, environmental remediation, and electrochemical devices due to its bandgap properties and oxidizing capability. The material is notable for its potential in water treatment and air purification systems where its strong oxidizing power can decompose pollutants, though it remains less common in mainstream industrial production compared to more established photocatalytic materials like TiO2.

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.
