Problems solved by technology

[0002] Research on heat-resistant ceramics has always been a difficult problem in the field of daily-use ceramics. The existing heat-resistant ceramic products have the following disadvantages: First, the heat-resistant temperature can only reach 400-600 ° C. When consumers use this type of ceramic products, Often the ingredients are almost cooked, and the ceramic products will crack, which not only wastes ingredients, but also poses a great safety hazard; second, the thermal expansion coefficient is high, the thermal shock resistance is poor, and the heat exchange is easy to break, so it cannot be used in harsh environments.

Description

technical field [0001] The invention relates to high heat-resistant ceramics and a preparation method thereof. Background technique [0002] Research on heat-resistant ceramics has always been a difficult problem in the field of daily-use ceramics. The existing heat-resistant ceramic products have the following disadvantages: First, the heat-resistant temperature can only reach 400-600 ° C. When consumers use this type of ceramic products, Often the ingredients are almost cooked, and the ceramic products will crack, which not only wastes ingredients, but also has great safety hazards; second, the thermal expansion coefficient is high, the thermal shock resistance is poor, and the heat exchange is easy to break, so it cannot be used in harsh environments. use below. Contents of the invention [0003] Aiming at the shortcomings of the prior art, the invention provides a high heat-resistant ceramic and a preparation method thereof. [0004] In order to solve the problems of...
