Vanadium Flake And Powder

It can be used in the manufacture of dyes and coloring materials for ceramics, paints, UV-opaque glass, and photographic developers. It is predicted that it will be widely used in medicine, pesticides and prevention of plant diseases.

The production methods of vanadium pentoxide vary depending on the source of raw materials. At present, the production methods used at home and abroad can be summarized as alkali melting method, salt melting method, and ion exchange resin method. The alkali fusion method uses high-temperature roasting of vanadium powder and soda ash to generate sodium metavanadate, which is then neutralized by adding sulfuric acid under heating and stirring to produce vanadium pentoxide.

V₂o₅ Flakes

The salt fusion method uses vanadium ore and industrial salt to be ball milled and then oxidized and roasted to obtain sodium metavanadate, which is then acidified with hydrochloric acid to produce vanadium pentoxide products. This is currently the most commonly used method in industry.

Although people switched to the calcification roasting method to solve the problem of the generation of polluting waste gas, it exists in the form of calcium salt after roasting with limestone, which requires higher conditions in post-processing and also brings certain difficulties to production. The ion exchange resin method solves the pollution problem of hydrochloric acid wastewater, but the cost of ion exchange resin is relatively high and difficult to produce on a large scale, and the regeneration of ion exchange resin also requires a certain amount of money.
