The present invention provides a zirconia pre-calcined body which exhibits a suitable color tone by firing in a short time. The present invention relates to a zirconia pre-calcined body, comprising zirconia whose main crystal system is monoclinic and a stabilizer capable of suppressing zirconia transformation, extending in a first direction from one end to the other end of the zirconia pre-calcined body On the straight line, the (L*, a*, b*) after sintering of the L*a*b* colorimetric system at the first point in the section from the one end to 25% of the total length is written as ( L1, a1, b1), and (L*, a*, b*) after sintering at the second point in the section from the other end to 25% of the total length is written as (L2, a2, b2 ), L1, a1, b1, L2, a2, and b2 are within the specified range, L1>L2, a1<a2, b1<b2, after sintering from the first point to the second point (L*, a*, The tendency to increase or decrease b*) does not change. |
