Abstract
A method for producing a stabilizing element-containing zirconia sintered body includes heating a zirconia compositional substance containing a stabilizing element from a heating start temperature to a first target temperature of 800° C. or higher and lower than 1400° C. at a heating rate of 150° C./minute or more; elevating the temperature from the first target temperature to a second target temperature of 1400° C. or higher and lower than 1580° C. at a heating rate of more than 30° C./minute and less than 200° C./minute; and retaining the second target temperature.
