Problems solved by technology

[0002] Ceramics have a long history of use in our country, and are now widely used all over the world. Daily-use ceramics have become an indispensable part of people's daily life. All kinds of tableware, tea sets, and various sanitary ware can be seen everywhere. These ceramics It is not only beautiful and generous, but also has the advantages of easy cleaning, temperature resistance, wear resistance and corrosion resistance, etc., and is deeply loved by consumers. However, ceramic products are generally brittle, not resistant to impact, poor toughness, uneven glaze color and easy to fall off. , high production energy consumption and other shortcomings, resulting in serious damage in the process of production, transportation and application, thereby increasing production costs. Therefore, it is urgent to improve its performance and promote the development of the daily-use ceramics industry in the direction of low cost and green environmental protection.
[0003] Due to the large thermal expansion coefficient, poor toughness and wear resistance of ordinary ceramics, it is easy to break under high temperature environment, so its application field is greatly limited, and it cannot be used in high temperature parts, especially in parts with frequent alternating hot and cold
