TUNGSTEN CAS:13472-45-2 Product introduction
Product name: Sodium tungstate
CAS: 13472-45-2
MW:225.85
MF: H3NaOW
Appearance: white opaque crystal block
TUNGSTEN Characteristic:
Sodium tungstate anhydrous is a white opaque crystalline block with three crystal forms of δ, γ, and β. The transition temperature from δ to γ is about 570 °C, and from γ to β is about 585 °C. The relative density of Chemicalbook is 4.18 (18.5 °C), melting point 700 °C. In hydrogen, it does not change even when heated to 700°C, and it becomes metallic tungsten when it reaches 1100°C.
