Abstract

The invention relates to a nano-vanadium-zirconium blue ceramic colorant and a preparation method thereof. The nano-vanadium-zirconium blue ceramic colorant is made of the following raw materials in parts by weight: 8-15 parts of vanadium pentoxide, 30-50 parts of zirconium oxychloride 30-45 parts of sodium silicate, 25-40 parts of acid or strong acid and weak base salt, 1-2.5 parts of sodium chloride and 1-2.5 parts of sodium fluoride; the present invention uses sodium silicate, zirconium oxychloride, hydrogen Sodium oxide, vanadium pentoxide and acid or strong acid and weak base salt were used as initial raw materials, and water was used as solvent to synthesize vanadium-zirconium blue gel precursor by sol-gel method, and sodium chloride and sodium fluoride were used as composite minerals A nano-vanadium-zirconium blue ceramic pigment was prepared by low-temperature sintering; the obtained pigment has pure color tone, low firing temperature, low energy consumption, low-cost and easy-to-obtain raw materials, simple and easy-to-control production process, and the solvent environment used Friendly, the product is loose and easy to powder, the color rendering effect is good, and it is convenient for industrial production. It is an ideal color material for the production and firing of high-quality ceramic products.

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, domestic and foreign scholars have done a lot of research work on fine ceramic pigments and have achieved remarkable results. As a high-quality pigment with high temperature resistance, pure color and high thermal stability, zirconium-based pigments have received widespread attention from ceramic workers. With the unremitting efforts of ceramic pigment researchers, a large number of zirconium pigments have emerged. The research and development, production and application of these pigments have brought prosperity to the development of the ceramic industry, but also brought severe challenges to the increasingly tense energy demand and the deteriorating environment. Therefore, the development of a batch of low energy consumption and environmental...
