Into organic solvent, then the methyl isobutyl ketone containing fluorine niobic acid or sec-octyl alcohol solution are stripped using pure water,
Fluorine niobic acid is entered in pure water solution, is neutralized, filtered by ammonia, washed, dried, roasted and prepare high purity niobium oxide.
7. a kind of production method of alloying metal zine plate material, it is characterised in that：Include the following steps：
1) stock up：Each material component is weighed by composition of raw materials ratio, it is spare；
2) melting kirsite：Zinc is added in by being preheated in 600-700 DEG C of smelting furnace, after stirring evenly, smelting furnace is warming up to 1800-
2000 DEG C, aluminium, copper, pure magnesium, iron, high purity titanium, carbon, pure silicon, manganese, cadmium telluride, crystal whisker of gypsum, niobium oxide and ytterbium are being sequentially added,
After stirring to complete melt, zinc liquid is made；
3) alloying metal zine plate is molded：Manufactured zinc liquid is injected in mold, after cooling, the first alloying metal zine plate is made
Crude green body；
4) alloying metal zine plate forges：First alloying metal zine plate crude green body is pressed repeatedly, the second alloying metal zinc is made
Plate crude green body；
5) alloying metal zine plate is modified：It polishes manufactured second alloying metal zine plate crude green body, metal zine plate is made；
6) library storage is entered：Manufactured golden metal zine plate is carried out into library storage.
