Problems solved by technology

Most of the traditional ceramic glazes are made of slurry, and then evenly applied to the green body for sintering. This method has complicated processes when preparing the glaze slurry, and it requires very uniform coating on the green body, and the process is also relatively complicated.

Abstract

The invention discloses a method for preparing a water soluble yellow ceramic glaze. The method is characterized by comprising the following steps: adding 35-45% of ammonium fluozirconate, 1.0-2.0% of carboxymethyl cellulose, 20-30% of ammonium fluosilicate, 1-5% of ammonium dichromate, 10-25% of ammonium fluoroborate, 5-15% of praseodymium chloride in a reactor, wherein the sum of components is 100%, grinding and mixing uniformly to obtain the water soluble yellow ceramic glaze. The obtained water soluble yellow ceramic glaze is packaged by a plastic product and sealed to keep away from moisture. The using method of the water soluble yellow ceramic glaze is as follows: dissolving the water soluble yellow ceramic glaze in hot water with the mass concentration of 21-23% at the temperature of 50-60 DEG C, uniformly spraying the water soluble yellow ceramic glaze solution on a ceramic biscuit by a sprayer and sintering at 950-1050 DEG C to obtain the product.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a preparation method of water-soluble yellow ceramic glaze, which belongs to ceramic pigments and includes soluble additives and colorants. Background technique [0002] In China's splendid artistic culture for thousands of years, ceramic art has always occupied a relatively important position. As for ceramic art, the glaze is a key part. Generally speaking, the so-called ceramic glaze is a thin uniform glassy layer covering the surface of the ceramic body. For ceramic products, ceramic glazes can improve performance and play a decorative role. Yellow gives people a feeling of lightness, hope and firepower. It has excellent decorative effects and is loved by people. Therefore, developing the pure yellow color ceramic glaze of pure 'chemical stability' has always been a hot topic in the research of the ceramic pigment industry. Especially water-soluble yellow cera...
