Sodium Tungstate Dihydrate CAS#10213-10-2
Basic Information
white crystalline powder or colorless to white rhombic crystal
Sodium tungstate dihydrate is a white crystalline powder or colorless-to-white crystal with high water solubility and a weakly alkaline solution. The hydrate gradually loses crystal water on heating and forms tungstic acid precipitates with strong acids. It is used in steel electroplating, metal-surface treatment, petrochemical catalysis, tungsten-oxide and tungsten-carbide preparation, analytical testing, pharmaceutical research, and trace-element fertilizer systems.
