Hydrated tungstic acid
WebTungstic acid is a hydrated form of WO3 (tungsten trioxide). The modest form is monohydrate WO3·H2O and WO3·2H2O (dihydrate). The arrangement of WO3·H2O in the solid form comprises layers, which have octahedrally coordinated WO5(H2O) units and 4 vertices are shared. Web3 mrt. 2024 · The specific gravity of the solution is 1.30 ~ 1.45, and the acid precipitation mother liquid is adjusted to pH7 to 9. After stating, it is naturally filtered to separate the impurities such as SiO 2 and Fe. More than 99.5% of the WO 3 was dissolved in the solution, and most of the SiO 2 and most of the iron was removed. 5. Acid precipitation ...
