Beschreibung
Zusammenfassung:	A method for manufacturing ²-sialon, including: a mixing process wherein at least one of aluminum oxide and silicon oxide, silicon nitride, aluminum nitride, and europium compound are mixed; a burning process wherein the mixture having undergone the mixing process is heated at the temperature hither than 1950°C but not exceeding 2200°C for 10 hours or longer; and a heat treatment process wherein heat treatment is conducted after the burning process at the temperature from 1300°C to 1600°C in an atmosphere of inert gas other than nitrogen at the partial pressure of 10 kPa or lower.
