Abstract:
Provided is a zirconia sintered body that uses coloring of cerium oxide, the zirconia sintered body exhibiting a bright red color. The zirconia sintered body includes an oxide of cerium is an amount of 0.5% by mole or more and less than 4% by mole in terms of CeO 2 , yttria in an amount of 2% by mole or more and less than 6% by mole, an oxide of aluminum in an amount of 0.1% by weight or more and less than 2% by weight, and the balance being zirconia. The oxide of cerium contains trivalent cerium, and the zirconia has a crystal structure including a tetragonal phase.

Claim (Index 5):
A method for manufacturing the zirconia sintered body according to  claim 1 , the method comprising sintering, in a reducing atmosphere, a compact containing yttria in an amount of 2% by mole or more and less than 6% by mole, an oxide of cerium in an amount of 0.5% by mole or more and less than 4% by mole in terms of CeO 2 , an oxide of aluminum in an amount of 0.1% by weight or more and less than 2% by weight, and the balance being zirconia.
