Abstract

The invention relates to a method for preparing a coloring material by using manganese carbonate. The method comprises the following steps: performing surface modification treatment on manganese carbonate, performing decaying treatment on the surface-modified manganese carbonate at 30-50 DEG C for 48-60 hours, mixing the decayed manganese carbonate with auxiliary raw materials to form a mixture, heating at 80-100 DEG C / h, calcinating from 0 DEG C to 1,150 DEG C, and keeping warm at 1,130-1,200 DEG C for 1-2 hours, to obtain the coloring material. The method for preparing the coloring materialby using manganese carbonate can widen the calcinating range of the obtained coloring material, has good high temperature performance, and can be applied to high-end ceramic products.

Description

[0001] This case is a divisional application based on the invention patent with the application date of February 29, 2016, the application number 201610111336.4, and the title "A Method for Preparing Colorants Using Manganese Carbonate" as the parent case. technical field [0002] The invention relates to a color material production process, in particular to a method for preparing color material by utilizing manganese carbonate. Background technique [0003] At present, manganese carbonate is used as raw material in the ceramic pigment industry to produce pigments. Most of the pigments are pink pigments. The method of using manganese carbonate as a raw material to produce pink pigments in the prior art has a narrow firing range of pigments, and pinholes are prone to appear on the glaze surface when used in a temperature environment above 1250°C. , Weak tinting strength and not bright enough color tone, that is, the problem of poor use effect under high temperature environmen...
