Problems solved by technology

The solid phase sintering method is to repeatedly pulverize, wash, dry, and finely grind the massive color material obtained by solid phase sintering. Sometimes, in order to improve the stability and color strength of the color material, it needs to be fired twice or fired three times. Even more refiring processes, making the pigments expensive
Both sol-gel and precipitation methods have disadvantages such as cumbersome operation steps, high cost or lengthy process to varying degrees

Embodiment 1

[0013] 38.32 grams of zirconium nitrate, 6.01 grams of silicon dioxide and 21.69 grams of ammonium acetate were uniformly mixed, and then 2.35 grams of ammonium metavanadate were added and stirred uniformly to obtain a uniform mixture; 0.46 grams of sodium fluoride and 0.46 grams of Sodium fluorosilicate, fully grind to get a uniform mixture, put the mixture into a combustion vessel; put the mixture together with the vessel into a furnace at 550 ° C, a low-temperature combustion reaction occurs instantly, turn off the power, take out the vessel and cool it in the air After cooling, the vanadium-zirconium blue ceramic color material precursor is obtained; the precursor is calcined at 800° C. for 30 minutes, and the vanadium-zirconium blue ceramic color material with a particle size of less than 1 μm can be obtained.

Embodiment 2

[0015] 16.00 g of zirconium nitrate, 4.35 g of silicon dioxide, 5.60 g of urea and 5.60 g of citric acid were uniformly mixed, then 0.55 g of ammonium metavanadate and 0.50 g of vanadium pentoxide were added, and evenly stirred and mixed to obtain a uniform mixture. Add 0.15 grams of sodium fluoride and 0.15 grams of sodium chloride to the mixture, grind it thoroughly to obtain a uniform mixture, put the mixture into a combustion vessel; put the mixture into a furnace at 450°C together with the vessel, and a low temperature will occur instantly Combustion reaction, turn off the power, take out the vessel and cool it in the air, and obtain the vanadium-zirconium blue ceramic colorant precursor after cooling; calcinate the precursor at 900°C for 50 minutes to obtain the vanadium-zirconium blue ceramic colorant.

Embodiment 3

[0017] 38.32 grams of zirconium nitrate, 6.01 grams of superfine silicon dioxide, 11.80 grams of ammonium acetate and 12.60 grams of citric acid were uniformly mixed, and then 1.44 grams of vanadium pentoxide was added, and uniformly stirred and mixed to obtain a uniform mixture. Add 0.46 gram of sodium chloride and 0.46 gram of sodium fluorosilicate to the mixture, grind it thoroughly to obtain a uniform mixture, put the mixture into a combustion vessel; put the mixture into a furnace at 350°C together with the vessel, and A low-temperature combustion reaction occurs, the power is turned off, the vessel is taken out and cooled in the air, and the vanadium-zirconium blue ceramic colorant precursor is obtained after cooling; the precursor is calcined at 1000° C. for 20 minutes to obtain the vanadium-zirconium blue ceramic colorant.

Abstract

The invention discloses a method for preparing a zircon-vanadium blue ceramic pigment, and belongs to the technical field of fine ceramics. In the method, zirconium nitrate and silicon dioxide are respectively taken as a vanadium raw material and a silicon raw material, ammonium acetate and the like are taken as organic incendiary agents, vanadium pentoxide, ammonium metavanadate and the like aretaken as zircon raw materials, sodium chloride, sodium fluoride and sodium fluosilicate are taken as a composite mineralizer, and the zircon-vanadium blue ceramic pigment is prepared by combustion synthesis and calcining technology. The method has the advantages that: the production process is simple, the equipment requirement is low, and the method is suitable for industrial production. The prepared zircon-vanadium blue ceramic pigment has narrow size distribution and stable color.

Description

technical field [0001] The invention belongs to the technical field of fine ceramics, and in particular relates to a preparation method of a vanadium-zirconium blue ceramic pigment. Background technique [0002] At present, ceramic decoration has begun to use ceramic inkjet printing decoration technology, which makes ceramic ink into ceramic ink, and prints it directly onto the ceramic surface through a computer-controlled printer for decoration. Its advantage is that it can overcome the limitations of high technical requirements for operators, low production efficiency, and poor pattern reproducibility of hand-painted decoration technology; it can make up for the shortcomings of screen printing, rubber roller printing technology, etc. And the pattern is flexible, without the advantages of molds, etc., to meet the characteristic needs of individual production. The preparation of ceramic ink with stable performance is one of the key technologies of computer inkjet printing d...
