Abstract

The invention relates to a pigment production technology, in particular to a method for improving temperature resistance of a vanadium-zirconium blue pigment produced from fused zirconia, which comprises the following steps: step 1, screening zircon sand by using a 60-120M screen; step 2, performing high-temperature smelting treatment; step 3, drying the product obtained in the step 2, and screening by using a 10-30M screen; step 4, performing granularity control; and step 5, fully and uniformly mixing the obtained electric melting zirconium oxide with other raw materials of the ferrozirconium red pigment, heating and calcining, and cooling to obtain the yellow-red-tone ferrozirconium red pigment. The method has the beneficial effects that the zircon sand material and the smelted zirconium oxide particles are screened, so that the physical and chemical properties of the electric smelting zirconium oxide are improved, the temperature resistance of the vanadium-zirconium blue pigment is improved, and the color development effect requirements of products used in the fields are met; and the defect of common electric melting zirconium oxide in the aspect of temperature resistance of the vanadium-zirconium blue pigment is overcome, and the color of a ceramic product is enriched.

Description

technical field [0001] The invention relates to pigment production technology, in particular to a method for improving the temperature resistance of vanadium-zirconium blue material produced by electric fusion zirconia. Background technique [0002] At present, the ceramic glaze water temperature of the vanadium-zirconium blue material used in the ceramic industry is mostly above 1250°C. The vanadium-zirconium blue material made of ordinary fused zirconium is not resistant to temperature, and the fading is obvious when used in an environment above 1250°C, so it is not suitable for the above fields. application requirements. Specifically, under the same conditions, using the same vanadium-zirconium blue material production process, the vanadium-zirconium blue material made of ordinary fused zirconia will fade more obviously in high-temperature environments, and the temperature resistance effect is not ideal, and it cannot reach high temperature. Required ceramic products dem...
