Fluorescent ceramic pigment and manufacturing method thereof
The invention relates to a fluorescent ceramic pigment and a manufacturing method thereof, and belongs to the technical field of ceramic pigment preparation. The fluorescent ceramic pigment comprises the following raw materials in parts by weight: 1-5 parts of fluorescent pigment, 0.1-0.5 part of silicon dioxide, 10-20 parts of aluminum oxide, 20-30 parts of citric acid, 1-5 parts of sodium fluoride and 1-5 parts of sodium fluosilicate. The manufacturing method comprises the steps: uniformly mixing and stirring the raw materials to obtain a uniform mixture, and completely grinding the mixture for 2-4 hours; calcinating the mixture at 600-650 DEG C for 8-10 hours, thereby obtaining powder; adding the powder to purified water with the 20-25 times of the weight of the powder, stirring for 30-60 minutes to filter water, and drying; grinding the dried solid by a ball grinder, and screening by a sieve with 350-400 meshes, thereby obtaining the fluorescent ceramic pigment. The obtained fluorescent ceramic pigment has the advantages that the particle size distribution is narrow, the color generation is stable, the chromatic aberration is small, and the stability at high temperature is great; furthermore, the production process is simple, the device requirement is low, and the industrial production is easy to achieve.
