Problems solved by technology

Although there are many kinds of red materials, most of them contain toxic elements, or many of them will decompose or become unstable when the temperature exceeds a certain temperature. The wrapping technology for the high temperature stability of the material also needs to further improve its wrapping rate

Abstract

The invention relates to a zirconium phosphate high-temperature nickel red ceramic pigment and a preparation method of the pigment. The pigment employs industrial chemical materials, takes 55-60.8wt% of diammonium phosphate ((NH4)2HPO4) and 39.2-45wt% of zirconium oxide (ZrO2) as major raw materials and 2-7wt% of black nickel oxide (Ni2O3) as a colorant. The high-temperature nickel red ceramic pigment is prepared via burdening, water adding for stirring and mixing, drying, grinding, sieving, roasting, crushing, washing, baking, crushing and drying. The chemical materials adopted by the pigment are low in cost; the obtained nickel red pigment is bright in color and stable in color generation, can be widely used in various high-temperature ceramic products; and at the same time, since zirconium phosphate has small thermal expansivity, belongs to a low-expansion material and is very beneficial for thermal stability of a material applying zirconium phosphate, the pigment has wide application prospects.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials (ceramics), in particular to a zirconium phosphate high-temperature nickel-red ceramic pigment and a preparation method thereof. Background technique [0002] China is the world's largest producer of daily-use ceramics (including arts and crafts porcelain). It is also a major producer of architectural ceramics and sanitary ceramics in the world. According to preliminary estimates, my country's ceramic industry needs about 100,000 tons of glaze pigments, 200,000 tons of blank pigments, and 800,000 tons of frits. Glaze output is about 200,000 tons. This shows that the demand of the ceramic color glaze as above-mentioned ceramic product decoration material is quite large. At present, there are many ceramic pigments named after red in ceramic production. Red ceramic pigments are widely used in ceramic production. Red ceramic pigments have always been the research focus of ceramic worke...
