When zirconium oxide partially stabilized by yttrium oxide is added in excess of ζ, the fracture toughness value decreases.

る。In aluminum oxide-based ceramic sintered bodies, the fracture energy is absorbed as the transformation energy of partially stabilized zirconium by italium oxide, which undergoes a phase transformation from a tetragonal to monoclinic crystal, or the fracture energy is absorbed as the transformation energy of the phase transformation of partially stabilized zirconium by italium oxide, or the crack propagation occurs at the time of fracture. It is thought that the fracture toughness value improves because the energy of the pinning effect that occurs when the zirconium oxide hits the zirconium and branches due to the addition of yttrium oxide.

If the sintering time is shorter than 1 hour, a dense sintered body cannot be obtained, and if it exceeds 3 hours, the sintered body becomes overfired and its strength decreases.

'C for 2 hours to obtain a sintered body. A test piece of 4 x 3 x 3 (1-) was prepared from the sintered body and the fracture toughness was measured by the notch method.
The fracture toughness value of the conventional aluminum oxide sintered body consisting of 99% aluminum oxide and unavoidable impurities is 2~
It can be seen that this is significantly improved compared to 2.5 M N -m-t.
