What is the maximum temperature for ceramic rods?

Ordinary alumina or zirconia ceramics can withstand high temperatures above 1000 ° C when heated, while the peak temperature of advanced ceramics such as silicon carbide ceramics and silicon nitride ceramics can reach more than 1500 ° C. According to the material classification of ceramics, their ability to withstand high temperatures is different.

In the high temperature state, the rod can still maintain good physical properties, do not melt, maintain wear resistance, strength, insulation and so on.

Whether it is in the use of high-strength environment resulting in high temperature of the rod or in the case of high voltage resulting in heat, the high temperature resistance of the rod is still better than most metals.

The high temperature resistance of industrial ceramics is stronger, and some types of industrial ceramics can withstand high temperatures of about 2600 degrees.

For example, the melting point of alumina ceramics is 2050℃, and the boiling point is as high as 3000℃. This ceramic is favored in industrial applications for its excellent heat resistance.
