ZrO2 Ceramic Ball ZrO2 Ceramic Ball at routine temperature has high intension and
tenacity, good wearing resistance, high temperature resistance,
anti-canker, high rigidity, no magnetism, isolation for
electricity. At 600℃, the intension and rigidity almost could not
be changed, whose density is 6.00g/cm3, ZrO2 Ceramic Ball’s thermal
expansion rate is close to metal expansion rate, and could be used
in the joint with metal. ZrO2 Ceramic Ball at routine temperature has high intension and
