Document Type and Number:
Japanese Patent JP6978925
Kind Code:
B2
Abstract:
To provide a zirconia calcined body for dentistry which suppresses reduction of light transmissivity of a sintered body when main sintering is performed even when wet processing is performed using a contaminated cooling solvent, in which crack or the like does not occur compared with a case when a normal zirconia calcined body is subjected to dry processing and then main sintering is performed and equal light transmissivity is acquired.SOLUTION: There is provided a zirconia calcined body for dentistry in which, an impregnation material satisfying the following (A), (B), (C) is impregnated: (A) the impregnation material is a solid body at 25°C; (B) the impregnation material has hydrophobic nature; (C) a boiling point of the impregnation material is equal to or less than a proper firing temperature of the zirconia calcined body.SELECTED DRAWING: None
