Technical Field

The invention relates to the technical field of ceramic glaze, in particular to yellow high-gloss glaze for ceramics and a preparation method thereof.

Background

The yellow glaze occupies an important position in the ancient ceramic art, but China does not use a lot of yellow glaze in ancient times, and along with the development of the society, the yellow glaze slowly enters the ancient times and is used by common people to become a bright color in daily porcelain, but most of the yellow glaze on the market is not good in color, brightness and vividness.

The Chinese patent with the publication number of CN102491793B discloses a yellow high-gloss glaze for ceramics, which consists of 30-50 parts of potassium feldspar, 20-40 parts of quartz, 5-15 parts of marble, 8-15 parts of kaolin, 6-10 parts of transparent frit, 1-4 parts of cerium oxide, 1-4 parts of niobium oxide, 4-12 parts of a yellow pigment and 50-70 parts of water; the preparation method comprises the steps of uniformly mixing 30-50 parts of potassium feldspar, 20-40 parts of quartz, 5-15 parts of marble, 8-15 parts of kaolin, 6-10 parts of transparent frit and 50-70 parts of water, carrying out ball milling for 15-20 hours until the fineness reaches 325 meshes, uniformly mixing 1-4 parts of cerium oxide, 1-4 parts of niobium oxide and 4-12 parts of yellow pigment, carrying out ball milling until the fineness reaches 325 meshes, and finally uniformly mixing the two to obtain the yellow high-gloss glaze for ceramics.

However, in the process of practical production of the glaze in the above technical scheme, the inventors of the present invention have observed that the brightness of the glaze cannot reach an excellent level, and therefore, through research, the inventors have found that although the niobium oxide in the above technical scheme is added to the glaze, the surface of the ceramic can have a high refractive index, so as to increase the brightness of the yellow glaze surface, the requirement of the niobium oxide for color elements is high, and cerium oxide as a colorant in the above technical scheme cannot be well matched with niobium oxide, so that the crystallization effect of niobium oxide under an acidic condition is affected, and finally the brightness of the yellow glaze surface cannot reach an excellent level.
