Abstract

The invention discloses color-unchangeable lead-containing opalescent frit which is prepared from the following raw materials in part by weight: 40-50 parts of SiO2, 5-10 parts of Al2O3, 1-5 parts of CaO, 30-40 parts of PbO, 1-5 parts of ZrO2 and 1-5 parts of alkali metal. The color-unchangeable lead-containing opalescent frit disclosed by the invention has the beneficial effects that the composition proportion is determined through a lot of experimental screening, experimental results show that all the components are more scientifically and reasonably proportioned, ceramics prepared by the frit disclosed by the invention has good glazed smoothness, good enamel, uniform opalescence and wide application scope.

Description

[0001] technical field [0002] The invention relates to a frit for preparing ceramics, in particular to a non-discoloring lead-containing opalescent frit for ceramics. Background technique [0003] With the rapid development of the economy and the improvement of people's living standards, ceramic products have become indispensable products for people. However, the frits used for pottery making in the prior art generally have low density, poor covering ability, and narrow firing range. Disadvantages such as easy discoloration. Therefore, be very necessary on the basis of prior art, develop and design a kind of good enamel, uniform color and luster, good enamel, the lead-containing opalescent frit that does not change color. Contents of the invention [0004] Purpose of the invention: The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a glaze with good smoothness, good enamel, especially uniform milky wh...
