A zirconia ceramic disc is a round thin sheet made of zirconia. It has many good properties.
First, the zirconia ceramic disc has extremely high hardness and excellent wear resistance, and can withstand high temperature and high pressure environments. Secondly, it has excellent chemical stability and will not be corroded by chemicals such as acids and alkalis. In addition, zirconia ceramic discs also have good insulation properties and low thermal conductivity, and can work stably in high temperature environments.
Zirconia ceramic discs are often used in precision instruments, optical devices, electronic components and other fields because of their good insulation performance and high temperature stability.
