Abstract
The invention discloses a process for producing ultrafine bismuth vanadate. The process is characterized by comprising the steps of dissolving bismuth nitrate in an aqueous solution of nitric acid to obtain a bismuth nitrate solution; dissolving ammonium vanadate in an aqueous solution of nitric acid to obtain an aqueous solution of ammonium vanadate; atomizing and mixing the bismuth nitrate solution and the aqueous solution of ammonium vanadate in a sealed container, and adding ammonia water dropwise and stirring to adjust the pH value of the reaction solution; allowing a full reaction and precipitation at room temperature, filtering, washing and drying the precipitate to obtain a yellow powder; calcining and classifying the powder to obtain the ultrafine bismuth vanadate.
Description
Technical field
The invention belongs to the production technical field of mineral dye.
Background technology
Pucherite is a kind of Yellow organic dye, and is nontoxic, is the substitute of lead and yellow-collation, chrome yellow, cadmium yellow pigment.
Patent literature has been arranged some preparation methods of pucherite.A kind of preparation method of super-fine vanadic-acid bismuth-yellow pigment is disclosed as Chinese patent 200710095910.2, Chinese patent 200710061841.3 discloses the production technique of high-temp resistant bismuth vanadate yellow ceramic pigment, and Chinese patent 201010232638.X discloses a kind of environmental-friendly pigment bismuth yellow and production method thereof.
Above-mentioned preparation method all can prepare bismuth vanadate yellow pigment, but product particle is larger, and the pucherite area coverage of unit weight is less, the pigment applications cost is higher.Therefore, tiny, the technology of preparing evengranular bismuth vanadate yellow pigment of exploitation particle has great importance.
Summary of the invention
The present invention is directed to the above-mentioned shortcoming that exists in present bismuth vanadium pigments preparation process, the exploitation particle is tiny, evengranular pucherite manufacture craft.Technical scheme of the present invention is: Bismuth trinitrate is dissolved in aqueous nitric acid, obtain bismuth nitrate solution, vanadic acid ammonia is dissolved in aqueous nitric acid, obtain the vanadic acid ammonia soln, with the mixing that atomizes in encloses container of the Bismuth trinitrate aqueous solution and vanadic acid ammonia soln, drip the pH value of ammoniacal liquor, stirring, conditioned reaction liquid, at normal temperatures fully reaction, fully precipitation, with throw out filtration, washing, drying, obtain yellow powder, with this powder calcining classification, obtain ultra-fine pucherite.
The invention has the advantages that: atomizing mixes, sufficient reacting, and the acquisition particle is little, evengranular bismuth vanadate yellow pigment.
Preferred forms
Bismuth trinitrate is dissolved in aqueous nitric acid, obtain the Bismuth trinitrate aqueous solution, more than concentration is adjusted into 2.1mol/L, vanadic acid ammonia is dissolved in aqueous nitric acid, obtain the vanadic acid ammonia soln, more than concentration is adjusted into 2.1mol/L, make V: the Bi mol ratio is 1: 1, with the mixing that atomizes in encloses container of the Bismuth trinitrate aqueous solution and vanadic acid ammonia soln, drip ammoniacal liquor, stir, the pH value of conditioned reaction liquid is 2 left and right, fully reaction at normal temperatures, precipitation is more than 25 hours, throw out is filtered, washing, dry, obtain yellow powder, with the thermal treatment 2 hours at 500 ℃ of left and right temperature of this powder, classification, obtain super-fine vanadic-acid bismuth-yellow look pigment.
Claims (1)
1. the manufacture craft of a ultra-fine pucherite, its technical process comprises: Bismuth trinitrate is dissolved in aqueous nitric acid, obtain bismuth nitrate solution, vanadic acid ammonia is dissolved in aqueous nitric acid, obtain the vanadic acid ammonia soln, with the mixing that atomizes in encloses container of the Bismuth trinitrate aqueous solution and vanadic acid ammonia soln, drip the pH value of ammoniacal liquor, stirring, conditioned reaction liquid, fully reaction at normal temperatures, fully precipitation, with throw out filtration, washing, drying, obtain yellow powder, with this powder calcining classification, obtain ultra-fine pucherite.
