Abstract
The invention relates to a glaze material used in the production process of ceramic products, in particular to a glaze material with fluxing agent. The glaze material comprises the following raw materials in parts by weight: 30-32 parts of quartz, 25-29 parts of potash feldspar, 2-4 parts of aluminium oxide, 13-15 parts of calcite, 4-6 parts of dolomite, 1-2.5 parts of zinc oxide, 3-4.5 parts of kaoline, 1-2.5 parts of fluxing agent, 9-11 parts of zirconium silicate and 1-2.5 parts of fusion cake. A part of zinc oxide is replaced with finished products in the ceramic glaze material disclosed by the invention so that the aim of greatly reducing the production cost while ensuring thermal stability is ensured is achieved. The ceramic glaze in which the fluxing agent is added has the advantages that the added fluxing agent plays a fluxing role, the expansion coefficient of the glaze material is reduced, the thermal stability of ceramic products is improved, and the quality of the ceramic products can be ensured.
Description
technical field [0001] The invention relates to a glaze used in the production process of ceramic products, in particular to a glaze added with flux. Background technique [0002] At present, the main function of zinc oxide in the glaze used in the production process of ceramic products is to flux, which can reduce the expansion coefficient of the glaze and improve the thermal stability of the product. However, the price of zinc oxide is expensive. In the mass production of ceramic products, due to the need to use a large amount of zinc oxide for fluxing, the production cost of ceramic products is greatly increased. the burden of production costs. Contents of the invention [0003] The present invention aims at the high cost and large dosage of zinc oxide in the glaze, which increases the product cost, and provides an additive additive that can reduce the production cost while ensuring the thermal stability of the product. Flux glaze. [0004] The technical solution ado...
