Method for manufacturing sintered compact and sintered compact

Abstract

A method for manufacturing a sintered compact is provided, the method including: providing α-sialon phosphor particles; providing a formed body including forming a raw material mixture obtained by mixing the α-sialon phosphor particles and yttrium oxide particles; placing the formed body in a container containing pyrolytic boron nitride; disposing a first lid containing pyrolytic boron nitride at an opening of the container; and obtaining a first sintered compact containing an α-sialon phosphor crystal phase by subjecting the formed body in the container having the opening closed with the first lid to primary firing at a temperature in a range of 1800° C. to 2000° C.
