摘要：

The electrical conduction behavior and phase transition temperature of Y2O3-stabilized ZrO2 Containing 10 and 30 MOI% Y2O3 were investigated in a temperature range 930-1270-degrees-C. In order to determine the phase transition temperature on the basis of the electrical conductance of samples, it is necessary to measure the conductance reducing temperature al a fixed rate. The conductance data obtained in such a manner were analyzed using the following equation: InGT = a(T-1)2 + b(T-1) + c, where G is the conductance. The conductance data gave excellent agreement with the above equation not only in the fluorite-type phase region but also in the adjacent two-phase regions. The phase transition temperatures of 10 and 30 mol% Y2O3 compositions were about 1020-degrees-C and 1210-degrees-C, respectively.
