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.
