Problems solved by technology

[0007] In traditional ceramic production, glazes with lead and other heavy metal raw materials as the main components have excellent properties such as excellent melting performance, good high-temperature fluidity, high refractive index, good gloss on the glaze surface, and wide firing range; however, lead Glaze products are easy to precipitate lead during people's daily use, which is harmful to the health of users
In addition, the required glaze firing temperature is high. Traditionally, the "quasi-non-reaction" sintering mechanism is used to promote the liquid phase to produce a glossy and transparent glaze at a lower temperature stage, and it is difficult to meet the requirements without raw materials participating in high-temperature physical and chemical reactions. Gloss reduction

Abstract

The invention discloses a low-temperature transparent glaze, a ceramic product with the same and a preparation method. The low-temperature transparent glaze is prepared from, by weight, 28-35 parts ofanorthite powder, 20-26 parts of albite powder, 6-10 parts of sericite powder, 15-20 parts of metakaolin, 11-15 parts of calcined kaolin, 4-6 parts of washed soil, 7-11 parts of quartz, 5-8 parts ofhigh-silica bauxite powder and 2.5-3.5 parts of titanium oxide. The low-temperature transparent glaze is prepared from the carefully selected raw materials, so that the low-temperature transparent glaze or a ceramic product is formed on the surface of a prepared substrate through reasonable proportioning, almost no lead is dissolved out, and the low-temperature transparent glaze is healthy; the low-temperature transparent glaze fired at the low temperature and the ceramic product of the low-temperature transparent glaze have high whiteness and high glossiness; the low-temperature transparent glaze is pure, transparent and attractive.

Description

technical field [0001] The invention relates to the field of ceramic products, in particular to a low-temperature transparent glaze, a ceramic product with the glaze and a preparation method. Background technique [0002] Ceramic products are one of the most common utensils in people's daily life. The development history of ceramics is an important part of the history of Chinese civilization. Among them, the invention and development of ceramics have unique significance. With the development of modern science and technology, modern In the past century, many new ceramic varieties have appeared. They no longer use or rarely use traditional ceramic materials such as clay, feldspar, and quartz, but use other special materials, and even expand to the range of non-silicate and non-oxide. , and many new processes have appeared, making ceramics have various special functions. [0003] Fired ceramic products have many shortcomings of their own, and glazing can make up for these shor...
