Preparation method of heat-resisting solid solution blue and white porcelain

Abstract

The invention discloses a preparation method of heat-resisting solid solution blue and white porcelain, which mainly comprises the steps of raising temperature, drying, sintering, keeping warm, cooling, taking out from a kiln, and the like. The heat-resisting solid solution blue and white porcelain comprises the following components in percentage by weight: 20-65 percent of silicon dioxide, 0.01-1 percent of hydroquinone, 0.01-1 percent of zinc oxide, 0.05-2 percent of ammonium heptamolybdate, 0.01-2 percent of ethyl acetate, 15-35 percent of aluminium oxide, 0.1-3 percent of ferric oxide, 0.04-1.50 percent of trifluoroacetylacetone holmium, 5 to 10 percent of calcium oxide, 5-10 percent of magnesium oxide, 3-6 percent of potassium oxide, 1-5 percent of sodium oxide, 1-10 percent of lithium oxide, 0.01-2 percent of rutile type titanium dioxide, 0.06-2 percent of 1-bromine-3-methyl-2-butene and 0.01-1.55 percent of 3-ethyoxyl-4- carboxyl benzyl. According to the invention, the problem of high temperature oxidization during a firing process can be avoided in a better manner; a finished product is high in heat-resistant performance, and piezoelectric behavior can be shown; zero pollution can be caused, and the cost is low.

Description

technical field [0001] The invention relates to a preparation method of blue-and-white porcelain, in particular to a preparation method of heat-resistant solid solution blue-and-white porcelain. Background technique [0002] Blue and white porcelain (blue and white porcelain), often referred to as blue and white, is one of the mainstream varieties of Chinese porcelain. Blue and white is painted and decorated on white clay with natural cobalt, then covered with transparent glaze, and then fired at a high temperature of 1300 degrees Celsius, so that the color material can fully penetrate into the glaze, showing green and blue patterns. It looks quiet and beautiful, clean and elegant. For ordinary blue and white porcelain, when the fired products are heated during use, the thermal expansion coefficients of the body and the glaze are inconsistent, which will cause the glaze layer to crack, and in severe cases, the body will crack together. It cannot meet the quality requiremen...
