· Na2WO4

Sodium tungstate (Na2WO4) is an inorganic ceramic compound commonly produced as a white crystalline powder, valued for its chemical stability and moderate mechanical properties in solid form. It is primarily used as a precursor material in manufacturing tungsten-based ceramics and refractory compounds, and finds application in corrosion inhibition, catalysis support, and specialized coatings where tungsten's high density and thermal resistance are beneficial. Engineers select this material when cost-effective tungsten incorporation, chemical inertness, or precursor synthesis routes are priorities over pure tungsten alternatives.

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.
