[0024] ①Raw material processing: After mixing the raw materials evenly according to the proportion, dry them;

[0025] Described raw material is made up of following components by mass percentage:

[0026]

[0027] The Fe 2 o 3 、Al 2 o 3 , CaO, MgO, B 2 o 3 、Nd 2 o 3 , CrO 3 , CeO 2 The average particle size is 400nm;

[0028] ② Sintering: Put the raw materials in a crucible and treat them at 1200°C for 4 hours;

[0029] ③Post-processing: crush the product obtained in step ②, and pass through a 200-mesh sieve.

[0030] The obtained pigment is agate agate red material, which is stable under calcination at 1250°C.

Abstract

The invention relates to a method for preparing an agate red pigment, which belongs to the technical field of pigment preparation. In the method, Fe2O3, Al2O3, CaO, MgO, B2O3, Nd2O3, CrO3 and CeO2 are taken as raw materials, and a sintering method is utilized to prepare a ceramic pigment. The ceramic pigment has stable performance and crystal clear color at high temperature, is particularly suitable for coloring ceramic decorative materials and can be widely used for coloring ceramics.

Description

technical field [0001] The invention relates to a preparation method of agate red pigment, which belongs to the field of pigment preparation. Background technique [0002] Agate red material is bright in color and can be widely used in porcelain decorations and ceramic tiles. It is a good color material for decoration and one of the most widely used color materials. [0003] Glazes in ceramics are generally divided into overglaze pigments, underglaze pigments, and inglaze pigments. In the ceramic production process, these pigments are calcined at different temperatures, and the requirements for pigments with different uses are also different. For example, underglaze pigments need to be calcined at high temperature (above 1300°C), which requires high stability. But there are few varieties, and the earliest ones used are blue and white and underglaze red. Contents of the invention [0004] The object of the present invention is to provide a method for preparing agate red ...
