Abstract

The invention relates to a method for preparing an agate red ceramic glazing material, which belongs to the field of glazing material preparation. During the raw material treatment steps of the method, the glazing material comprises the following raw material components by weight percent: 50%-80% of base material, 15%-45% of pigment and 1%-5% of additive, wherein The pigment takes Fe2O3, Al2O3, CaO, MgO, B2O3, Nd2O3, CrO3 and CeO2 as raw materials and is prepared through utilizing a sintering method. The agate red ceramic glazing material which is prepared through utilizing the method has stable performance and crystal clear color at high temperature, and is particularly suitable for coloring ceramic decorative materials.

Description

technical field [0001] The invention relates to a preparation method of agate red ceramic glaze, which belongs to the field of glaze 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 ...
