A method for producing a cherry-colored zirconia sintered body, a cherry-colored zirconia powder, and a cherry-colored zirconia powder.

摘要

PROBLEM TO BE SOLVED: To provide a cherry-colored zirconia sintered body having high strength even when manufactured at a low molding pressure, bright in color, and well-balanced in color. SOLUTION: It contains zirconia, ittoria, elvia, alumina, zinc oxide and silica, and the content of itria is 0.7 mol% or more and 1.5 mol% or less, and the content of elvia is 0. When the content of alumina is 7 mol% or more and 1.5 mol% or less, the content of alumina is 0.1% by mass or more and 0.4% by mass or less, and the content of zinc oxide is 0.2% by mass or more and 0.3% by mass or less. A cherry-colored zirconia sintered body having a silica content of 0.05% by mass or more and 0.1% by mass or less and a relative sintering density of 99.5% or more. [Selection diagram] None
