Problems solved by technology

[0003] At present, due to the large thermal expansion coefficient, poor toughness and wear resistance of traditional ceramics, they are easily broken in high temperature environments, so their application fields are greatly limited and cannot be used in high temperature parts, especially in parts with frequent alternating hot and cold
With the development of kitchen utensil technology, the performance of ceramics has been improved, and the production of heat-resistant ceramics for kitchen utensils has been popularized and applied. The current heat-resistant ceramic kitchen utensils generally have low strength, poor thermal stability, and low operating temperature (only 400-600'C). Disadvantages, poor performance, so that the application is greatly restricted

Abstract

The invention discloses a heat-resisting ceramic for a cooking utensil. The heat-resisting ceramic is prepared from the raw materials in parts by weight: 10-15 parts of spinel, 10-20 parts of amazonite, 5-10 parts of apophyllite, 10-15 parts of chrysocolla, 20-25 parts of olivine, 20-30 parts of kaolin, 8-10 parts of silica, 1-3 parts of bentonite, 5-10 parts of graphite, 2-5 parts of ferric nitrate, 1-3 parts of potassium chloride, 2-50 parts of calcium carbonate, 5-10 parts of silicate and 10-15 parts of mica powder. After being sintered at high temperature, the heat-resisting ceramic for the cooking utensil has the characteristics of strong hardness, excellent corrosion resistance, thermal change resistance, thermal shock resistance, impact resistance and the like, is good in stability and is high in using temperature.

Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to a high-temperature-resistant ceramic material specially used for kitchen utensils. Background technique [0002] Ceramics, in terms of their materials, are divided into pottery, stoneware and porcelain, also commonly known as pottery, stoneware and porcelain. Ceramic is an advanced material state developed by natural materials through the practice of human production. Its physical and chemical properties are outstanding: its surface decoration methods are rich, acid rain resistance, good self-cleaning function, and the surface glaze has a translucent glass texture; Thousands of years of labor practice, with rich molding and manufacturing process means. [0003] At present, traditional ceramics are easily broken in high temperature environments due to their large thermal expansion coefficient, poor toughness, and poor wear resistance. Therefore, their application fields...
