High Purity Sodium Tungstate Dihydrate

High purity sodium tungstate dihydrate is a colorless or white crystalline powder that can be decomposed by strong acids into tungstic acid (water-insoluble). It is easily weathered in dry air. And it is stable in air, but heated to lose crystal water into anhydrous salt at 100°C. Besides, it is soluble in water and insoluble in ethanol.high purity sodium tungstate dihydrate image
High purity sodium tungstate dihydrate can be applied for the preparation of tungstic acid, and tungstate, etc. And it can also be used as analytical reagents, catalysts, water treatment agents, mordants, pigments, dyes, inks or fabric auxiliaries (To improve the waterproof and fireproof performance of fabric), and so on. Also, the sodium tungstate dihydrate can be used for corrosion resistance in electroplating coating (To improve the metal's corrosion resistance, wear resistance, hardness, conductivity, smoothness, heat resistance and surface appearance). Besides, it can be used for manufacturing the materials of oil industry, aviation and aerospace.
