Abstract

The invention relates to a nano vanadium-zirconium blue ceramic coloring material and a preparation method thereof. The nano vanadium-zirconium blue ceramic coloring material is prepared from the following raw materials in parts by weight: 8 to 15 parts of vanadium pentoxide, 30 to 50 parts of zirconium oxychloride, 30 to 45 parts of sodium silicate, 25 to 40 parts of acid or strong acid and weakalkali salt, 1 to 2.5 parts of sodium chloride and 1 to 2.5 parts of sodium fluoride. The nano vanadium-zirconium blue ceramic coloring material provided by the invention takes the sodium silicate, the zirconium oxychloride, sodium hydroxide, the vanadium pentoxide and the acid or strong acid and weak alkali salt are used as starting raw materials and water is used as a solvent; then a vanadium-zirconium blue gel precursor is synthesized through a sol-gel method; the sodium chloride and the sodium fluoride are used as a compound mineralizing agent and low-temperature sintering is carried out to prepare the nano vanadium-zirconium blue ceramic coloring material; the coloring material has the advantages of pure tone, low firing temperature, less energy consumption, cheap raw material price and easiness for obtaining the raw materials, simple and easy-to-control production technology, environment-friendly solvents, loose and easy-to-pulverize product, good coloring effect, convenience forindustrial production and the like and is an ideal coloring material for producing and firing a high-quality ceramic product.

Description

technical field [0001] The invention relates to the technical field of fine ceramic materials, in particular to a nano-vanadium-zirconium blue ceramic pigment and a preparation method thereof. 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 high-quality pigment with high temperature resistance, pure color and high thermal stability, zirconium-based pigments have attracted widespread attention from ceramic workers. With the unremitting efforts of ceramic pigment researchers, a large number of zirconium-based pigments came into being. The research and development, production and application of these pigments, while bringing prosperity to the development of the ceramic industry, have also brought severe challenges to the increasingly tight energy demand and the deteriorating environment. Therefore, the development of a batch of low energy consumption and e...
