· JVASP-111902· Na2W2O7

Sodium tungstate dihydrate (Na₂W₂O₇) is an inorganic ceramic compound belonging to the tungstate family, commonly used as a precursor material and functional ceramic in specialized industrial applications. It serves primary roles in catalysis, corrosion inhibition, and as a raw material for tungsten compound synthesis in chemical processing and manufacturing. Engineers select this material for applications requiring tungsten's high-temperature stability and chemical resistance, particularly in environments where tungstate-based coatings or catalytic functions are needed.

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.
