Medium-temperature high-white zirconium-lithium slurry opaque glaze and production method thereof

Abstract

The invention relates to a medium-temperature high-white-zirconium-lithium raw opalescent glaze and a production method thereof. The invention belongs to an opalescent glaze used for a ceramic product and a production method thereof. The invention mainly solves the technical difficulties of the prior opalescent glaze that the price is price; the cost is high; the fault of raw glaze surface can be easily produced; the color of the glaze surface is easily changed. A technical proposal adopted by the invention is the medium-temperature high-white-zirconium-lithium raw opalescent glaze which consists of feldspar, quartz, calcite, lithia porcelain, zircon powder, fluorite, talc, kaolin, trimeric sodium phosphate and additive, wherein, the weight percentages are 35 percent to 40 percent of feldspar, 10 percent to 15 percent of quartz, 5 percent to 10 percent of calcite, 12 percent to 15 percent of lithia porcelain, 10 percent to 15 percent of zircon powder, 1 percent to 2 percent of fluorite, 5 percent to 10 percent of the talc, 5 percent to 10 percent of kaolin, 0.1 percent to 0.2 percent of the trimeric sodium phosphate and 0.1 percent to 0.25 percent of additive. The production method of the invention consists of the steps as follows: firstly, the raw materials are washed and picked; secondly, the glaze materials are proportioned according to the weight percentages; thirdly, the glaze materials are processed for wet ball milling; fourthly, when the glaze materials is out from a mill, the glaze materials are processed for removing iron and sieving by strong magnet.

Description

technical field [0001] The invention relates to a medium-temperature high white zirconium lithium raw material opacity glaze and a production method thereof, belonging to an opacification glaze for ceramic products and a production method thereof. Background technique [0002] At present, opacifying glazes commonly used in ceramic products include tin oxide system opacifying glazes, zircon system opacifying glazes and titanium system opacifying glazes. Tin oxide system opacity glaze has good opacification effect, but the price of tin oxide is expensive and the cost is high. Zircon system opacity glaze, although the price of zircon is low, but its hardness is high, the grinding time is long, the viscosity of the glaze is high at high temperature, and it is easy to produce glaze defects. Titanium system opacity glaze is easy to precipitate anatase from the melt when firing at high temperature, causing the glaze surface to change color. Contents of the invention [0003] Th...
