SINTERED ZIRCONIA COMPACT AND ZIRCONIA COMPOSITION AND CALCINED COMPACT
지르코니아 소결체의 단면 사진에 있어서, 각 지르코니아 입자의 단면적을 기초로, 각 지르코니아 입자의 단면 형상이 원형이라고 가정한 경우의 환산 입경을 산출하고, 환산 입경을 기초로, 각 지르코니아 입자를 0.4 ㎛ 미만, 0.4 ㎛ 이상 0.76 ㎛ 미만 및 0.76 ㎛ 이상으로 클래스 분류하고, 각 클래스에 있어서, 단면적을 산출한 전체 지르코니아 입자의 총 단면적에 대한 각 클래스의 단면적 비율을 산출한 경우, 환산 입경이 0.4 ㎛ 미만인 지르코니아 입자의 단면적 비율이 4 ％ 이상 35 ％ 이하이고, 환산 입경이 0.4 ㎛ 이상 0.76 ㎛ 미만인 지르코니아 입자의 단면적 비율이 24 ％ 이상 57 ％ 이하이고, 환산 입경이 0.76 ㎛ 이상인 지르코니아 입자의 단면적 비율이 16 ％ 이상 62 ％ 이하이다.
When a cross-sectional area of each zirconia crystal grain is calculated in an image of a cross section of a zirconia sintered body; a converted crystal grain size of each zirconia crystal grain is calculated based on the cross-sectional area on the assumption that each zirconia crystal grain has a circular cross-sectional shape; the zirconia crystal grains are classified into a class of smaller than 0.4µm, a class of from 0.4µm to smaller than 0.76µm, and a class of 0.76µm or greater based on the converted crystal grain size; a total cross-sectional area of the zirconia crystal grains is calculated in each of the classes; and a rate of the cross-sectional area to a total cross-sectional area of all zirconia crystal grains whose cross-sectional area has been calculated is calculated in each class, the rate of the cross-sectional area of the zirconia crystal grains in the class of the converted crystal grain size of smaller than 0.4µm ranges from 4% to 35%, the rate of the cross-sectional area of the zirconia crystal grains in the class of the converted crystal grain size of from 0.4µm to smaller than 0.76µm ranges from 24% to 57%, and the rate of the cross-sectional area of the zirconia crystal grains in the class of the converted crystal grain size of 0.76µm or greater ranges from 16% to 62%.
