Problems solved by technology

[0003] With the gradual improvement of people's quality of life, ceramic products are used more and more widely, but the currently used colored ceramic products are prone to cracks and pinholes, and the substances in contact with them are easy to penetrate into cracks and pinholes during use, causing damage to ceramic products. Therefore, the lower density of the glaze obviously reduces the service life of ceramic products

Abstract

The invention mainly relates to the technical field of ceramic glaze processing, and discloses a high-density dark green glaze. The high-density dark green glaze is prepared from silicon dioxide, talcum powder, cerium oxide, lanthanum oxide, zirconium oxide, praseodymium oxide, cobaltous oxide, titanium dioxide, nano-zinc oxide, modified wollastonite, chlorite and table salt. The high-density darkgreen glaze is wide in raw material source, low in price, bright in color and fine in enamel, and has good fluidity and smearing performance, cracks and pinholes are avoided, the glaze surface is smooth and dense, and the grade of ceramic products is obviously improved. After the silicon dioxide, the talcum powder, the cerium oxide, the lanthanum oxide, the zirconium oxide and the praseodymium oxide are mixed and smashed, the mixture is firstly slowly heated and then rapidly heated, the praseodymium oxide is dark green through high-temperature heating, meanwhile, after the raw materials are heated at high temperature stage by stage, the fineness and the smoothness of the glaze can be improved, the density is high, and the cracks and the pinholes are avoided in the glazing process.

Description

technical field [0001] The invention mainly relates to the technical field of ceramic glaze processing, in particular to a high-density blue-green glaze. Background technique [0002] Glaze is a kind of silicate. The glaze applied on ceramics is generally made of quartz, feldspar, and clay. After grinding and adding water, it is coated on the surface of the green body and melted by roasting at a certain temperature. The temperature drops When forming a thin glassy layer on the surface of ceramics, it can increase the mechanical strength, thermal stability, dielectric strength of the ceramics and prevent the erosion of liquids and gases. effect. [0003] With the gradual improvement of people's quality of life, ceramic products are used more and more widely, but the currently used colored ceramic products are prone to cracks and pinholes, and the substances in contact with them are easy to penetrate into cracks and pinholes during use, causing damage to ceramic products.
