Problems solved by technology

[0002] As a traditional material with a long history, ceramics have been widely used in life or production a long time ago, but in terms of the current performance of ceramics, their heat resistance and thermal shock resistance are poor, and the temperature they withstand It is about 400-600°C, so if you don’t pay attention to controlling the process temperature during use or firing, ceramic cracking is prone to occur, and during use, due to the high brittleness of traditional ceramics, it cannot maintain good strength, so Usually encountering bumps can easily lead to ceramic cracking

Abstract

The invention discloses heat-resistant high-strength ceramic and a production technology and application thereof. The ceramic is prepared by compounding petalite, spodumene, calcium oxide, silica, zirconium boride, aluminum silicate fiber, feldspar, sodium humate, aluminum oxide an clay as raw materials and polyethylene glycol, carboxymethylcellulose and PAM as auxiliary materials; the prepared ceramic material has high heat resistance and high strength by combining the corresponding production technology. The ceramic is reliable in structural strength as a production material of artware, bumping damage in the transportation process can be avoided and the probability of falling damage in the playing process can be greatly reduced.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a heat-resistant high-strength ceramic and its production process and application. Background technique [0002] As a traditional material with a long history, ceramics have been widely used in life or production a long time ago, but in terms of the current performance of ceramics, their heat resistance and thermal shock resistance are poor, and the temperature they withstand It is about 400-600°C, so if you don’t pay attention to controlling the process temperature during use or firing, ceramic cracking is prone to occur, and during use, due to the high brittleness of traditional ceramics, it cannot maintain good strength, so Usually encountering bumps can easily lead to ceramic cracking. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a heat-resistant high-strength ceramic with high heat resista...
