Usage:
For the production of metal niobium raw materials, but also for optical glass and electronics industry
Manufacture of niobium salts and niobium metal, the preparation of standard solution. The electronics industry as a piezoelectric conductor material
Used as a nickel niobate single crystal, the system of special optical glass, high-frequency and low-frequency capacitors and piezoelectric ceramic components. Also used in the production of niobium and special steel needs of a variety of niobium alloys. Is the preparation of niobium and its compounds of raw materials. Also used as a catalyst, refractories.

Brief manufacture process:Roasted niobium or niobium oxide by the mixture of nitric acid and hydrofluoric acid dissolved fluoride niobium acid, with a strong acid and methyl isobutyl ketone mixture of organic extraction of niobium, and then after stripping, with ammonia and fluoride Niobium acid reaction of niobium hydroxide precipitation, and then washing, drying and burning, can be refined niobium pentoxide.
