TESTING STANDARD OF ZIRCONIA CERAMIC ROD

1. Observe whether the hardness of the ceramic rod meets the standard, and compare it with the preset data in a specific way. If the error is too large, it will be judged as unqualified. 2. At the same time, the thermal conductivity, wear resistance and corrosion resistance of the ceramic rod were measured. 3. The chemical stability of ceramic rods also needs to be measured in order to cope with special conditions, such as high or low temperature environment.
