Abstract

The invention discloses an easy-to-clean opal glaze suitable for low-expansion ceramics. The opal glaze is prepared from, by weight, 45-55% of petalite, 4-7% of kaolin, 25-35% of high-temperature low-expansion frits, 5-15% of high-temperature transparent frits, 0-10% of fine silicon powder and 3-6% of a glaze stabilizer. In addition, the invention also discloses a preparation method and application of the easy-to-clean opal glaze suitable for the low-expansion ceramics. The formulation system has a larger melting temperature range under an oxidizing atmosphere condition, which effectively solves the defect problems such as glaze face holes, and achieves the purpose of easy cleaning while having good stability. The preparation method can be based on a general production process of daily-useceramic glazes and daily-use ceramics, is suitable for various low-expansion ceramic green bodies, particularly provides a necessary condition for low-expansion ceramic pots matched with electric appliances, and has a promoting effect on the technological progress and application development of the low-expansion ceramic industry.

Description

technical field [0001] The invention relates to the technical field of ceramic glazes, in particular to an easy-to-clean milky white glaze suitable for low-expansion ceramics and a preparation method and application thereof. Background technique [0002] In the past ten years, the low-expansion ceramic industry has achieved considerable development with the support of the state and the efforts of enterprises, of which low-expansion ceramic cookware occupies a large proportion. With the continuous improvement of people's living standards and health requirements, ceramic cookware is more in line with the concept of health than the original iron cookware. Therefore, the demand for ceramic cookware is increasing, and the performance requirements are also increasing. high. Ceramic cooking utensils not only require aesthetics, but also pay more attention to their practicality, that is, certain functions. Especially in terms of cleaning, they need to have the characteristics of no...
