Vanadium zirconium blue ceramic pigment

Abstract

The invention relates to a vanadium zirconium blue ceramic pigment and belongs to the technical field of ceramic pigment processing. The vanadium zirconium blue ceramic pigment is prepared from the following components in parts by weight: 30-60 parts of zirconium nitrate, 20-50 parts of ultrafine silicon dioxide, 15-35 parts of ammonium metavanadate, 20-40 parts of ammonium acetate, 10-40 parts of absolute ethyl alcohol and 1-10 parts of mineralizer; the preparation method of the vanadium zirconium blue ceramic pigment comprises the following steps: weighing the components proportionally and mixing evenly, putting the mixture into an electric furnace of which the temperature is set for reacting, and continuously calcining to obtain the vanadium zirconium blue ceramic pigment; the average grain diameter of the ceramic pigment powder is 0.83 microns and the particle size distribution is concentrated; and the ceramic pigment is mixed with a glaze and fired, and then is stable and even in color generation and normal in color development.

Description

technical field [0001] The invention relates to a ceramic color material, in particular to a vanadium-zirconium blue ceramic color material, and belongs to the technical field of ceramic color material processing. Background technique [0002] Zirconium-based ceramic pigments are a series of ceramic pigments formed by zirconium silicate coloring matrix and different coloring ions. V-ZrSiO 4 Blue, Pr-ZrSiO 4 Yellow, Fe-ZrSiO 4 The red 3 large zirconium-based pigment series has become an important system of ceramic pigments, and constitutes the three primary colors of zirconium-based pigments. Zirconium-based pigments are widely used because of their abundant synthetic raw materials and low price. [0003] The traditional vanadium-zirconium blue ceramic pigment is famous for its high thermal stability, chemical stability, strong coloring ability and the ability to mix with most ceramic pigments to form composite colors. However, due to the large particle size of the color...

Problems solved by technology

At present, oxides such as CeO2, Al2O3 and composite oxides have been prepared by low-temperature combustion method. Nd: YAG transparent laser ceramic powder was prepared by this method, and Zhu Zhenfeng also successfully prepared Pr-CeO2 red rare earth pigment by this method, but the preparation of ultrafine vanadium-zirconium blue ceramic pigment by low-temperature combustion method no report

[0005]200910193838.6 discloses a method that uses zirconium nitrate and silicon dioxide as zirconium and silicon raw materials respectively, uses ammonium acetate as an organic combustion agent, and uses vanadium pentoxide, Ammonium metavanadate, etc. are used as vanadium raw materials, and sodium chloride, sodium fluoride, and sodium fluorosilicate are used as composite mineralizers. Through combustion synthesis and calcination processes, a vanadium-zirconium blue ceramic color is obtained. However, the method has high calcining temperature, high environmental pollution, and great environmental pollution; the present invention adopts the low-temperature calcining method to develop a vanadium-zirconium blue with simple production process, low equipment requirements, and easy industrial production Ceramic pigment, the prepared vanadium-zirconium blue ceramic pigment has narrow particle size distribution and stable color
