Niobium pentoxide Use and Manufacturing
Roasting method dissolves niobium material or crude niobium pentoxide in a mixture of nitric acid and hydrofluoric acid to generate fluoroniobic acid, extracts niobium with a mixture of strong acid and methyl isobutyl ketone organic phase, and after stripping, uses ammonia and fluorine Niobic acid reacts to generate niobium hydroxide precipitate, and then after washing, drying and burning, refined niobium pentoxide can be obtained. 3Nb+5HNO3+21HF→3H2NbF7+5NO+10H2OH2NbF7+7NH4OH→Nb(OH)5+7NH4F+2H2O2Nb(OH)5→2Nb(OH)5+5H2O
Used as a raw material for the production of metal niobium, and also used in the optical glass and electronic industries; used to pull nickel niobate single crystals to make special optical glass, high-frequency and low-frequency capacitors and piezoelectric ceramic components. It is also used to produce ferroniobium and various niobium alloys required for special steel. It is the raw material for preparing niobium and its compounds. It is also used as a catalyst and refractory material. Produce niobium salt and metal niobium, prepare standard solution. Electronic industry used as piezoelectric conductor material.
