Abstract

The invention relates to a preparation method of a cobalt-zinc green nano ceramic pigment. A sol-gel method is adopted for preparing a cobalt-zinc green pigment precursor, and the cobalt-zinc green nano ceramic pigment is prepared through low-temperature sintering; meanwhile, the used raw materials are low in cost and available, a production technology is simple and easy to control, and the used solvent is environment-friendly, so that industrial production can be conveniently realized; besides, the prepared cobalt-zinc green nano ceramic pigment has the advantages of pure hue, low sintering temperature, low energy consumption, looseness and easiness in smashing and is ideal for sintering a high-quality ceramic product.

Description

technical field [0001] The invention relates to the technical field of fine ceramic materials, in particular to a method for preparing a cobalt-zinc green nano-ceramic pigment. Background technique [0002] In recent years, scholars at home and abroad have done a lot of research work on fine ceramic pigments and achieved remarkable results. As a kind of high temperature resistance, good coloring effect, and simple and convenient glaze application method, cobalt-based pigments have attracted extensive attention from ceramic workers. With the efforts of ceramic pigment researchers, a large number of cobalt-based pigments came into being. However, the research on cobalt-based pigments mainly focuses on cobalt blue materials and some cobalt green materials (such as cobalt-titanium green, titanium-cobalt green materials), and cobalt-zinc green nano-color materials have not been reported yet. Contents of the invention [0003] The purpose of the present invention is to provide...
