Abstract

The invention discloses a medium-temperature heat-resistant ceramic product and a production method thereof. The product comprises a heat-resistant ceramic body and a heat-resistant ceramic glaze surface layer, and the heat-resistant ceramic body is prepared from, by weight, 40-50 parts of lepidolite, 25-35 parts of aluminum oxide, 15-19 parts of kaolin and 7-9 parts of bentonite. The heat-resistant ceramic glaze surface layer is prepared from, by weight, 55-65 parts of albite, 9-11 parts of light calcium carbonate, 8-12 parts of spodumene, 8.5-11 parts of zinc oxide, 4-6 parts of raw talc, 4-7 parts of kaolin and 3-5 parts of boron nitride fibers. According to the product, forming raw materials of the heat-resistant ceramic body and the heat-resistant ceramic glaze surface layer are selected, the matching ratio of the forming raw materials of the heat-resistant ceramic body and the heat-resistant ceramic glaze surface layer is optimized, the problems of nonuniform mixing and matchingcaused by more raw materials are reduced, quality stability of the ceramic product is improved, and the prepared medium-temperature heat-resistant ceramic product is small in heat expansion coefficient, good in thermal shock resistance and high in compressive strength.

Description

technical field [0001] The invention relates to the field of ceramic products, in particular to a medium-temperature heat-resistant ceramic product and a preparation method thereof. Background technique [0002] Ceramic materials are a class of inorganic non-metallic materials made of natural or synthetic compounds through shaping and high-temperature sintering. It has the advantages of high melting point, high hardness, high wear resistance and oxidation resistance. It can be used as structural material, tool material, and because ceramics also have some special properties, they can also be used as functional materials. [0003] The production of daily-use ceramics can be said to be due to people's needs for daily life. In daily life, people have the most contact with and are most familiar with porcelain, such as tableware, tea set, coffee set, wine set, and table set. [0004] However, the currently used ceramics still have at least the following problems: 1. The heat re...
