Abstract

The invention relates to red ceramic pigment and a preparation method thereof and belongs to the technical field of ceramic pigment preparation. The red ceramic pigment is prepared from, by weight, 0.1-0.5 part of ferric oxide, 1-5 parts of chromic nitrate, 1-5 parts of aluminum nitrate, 0.5-1 part of silicon dioxide, 5-10 parts of zinc oxide, 25-35 parts of urea, 0.1-0.5 part of sodium fluoride and 15-20 parts of sodium fluosilicate. The preparation method includes the steps that the raw materials are evenly mixed and stirred to obtain a uniform mixture, and the mixture is fully ground for 2.5-3 hours; the mixture is forged for 5-6 hours at the temperature of 700-750 DEG C; after forging, the powder is added into pure water with the weight 20-25 times that of the powder, stirred for 30-60 min, drained and dried; the dried solid is ground through a ball mill, passes a screen with 300-350 meshes, and the red ceramic pigment is obtained. The ceramic pigment is narrow in particle size distribution, stable in color generation, little in color difference change and good in stability at high temperature. Meanwhile, the production technology is simple in process, equipment requirements are low, and industrial production is easy to achieve.

Description

technical field [0001] The invention relates to a ceramic color material, in particular to a red ceramic color material and a preparation method thereof, belonging to the technical field of ceramic color material preparation. Background technique [0002] Ceramic pigments, also known as pigments or color materials, are powdery decorative materials for colored ceramics formulated with color bases and fluxes or additives. Pigment = color base + flux, the color base is the chromogenic substance and other raw materials, and the flux is the silicate substance with a low melting point. [0003] The role of ceramic pigments includes three aspects: (1) body coloring: mixing the colorant with the body to make the body present a certain color after firing; (2) coloring of the glaze: the coloring agent and the basic glaze can be used Blending various color glazes and artistic glazes; (3) Drawing patterns: it is widely used for manual painting on the surface and under glaze of the glaz...
