Wolframite From Acidic System Decomposition

decomposition of wolframite in acidic system

At present, the main method of industrial decomposition of tungsten mineral raw materials is NaOH decomposition process, which must be under extreme conditions (high temperature, high pressure and high alkali) to achieve effective decomposition of tungsten ore. However, the tendency of thermodynamic reaction of acid decomposition of tungsten ore is very high, but the decomposition is often incomplete due to the kinetic constraints.

Metal tungstates are a kind of important inorganic materials. They have good application prospects in optical fibers, scintillation materials, photoluminescent materials, humidity sensors, magnetic devices, microwave applications, catalysts and corrosion inhibitors. Among them, zinc tungstate nanomaterials are good materials for photoluminescence, photocatalysis and gas sensing. However, pure zinc tungstate nanomaterials are less sensitive to hydrogen.
