METHOD FOR IMPROVING RESISTANCE TO HIGH TEMPERATURE REACTION OF SIALON MATERIAL, METHOD FOR PRODUCING SIALON MATERIAL USING THE SAME, AND SIALON CERAMICS TOOL
To provide a method for improving resistance to high temperature reaction of a sialon material.SOLUTION: A method for improving resistance to high temperature reaction of a sialon material includes a step of heat-treating the sialon material at temperature of 1,200 to less than 1,400°C under oxygen-containing circumstances to form an oxide film on the surface of the material, the oxide film containing mullite, quartz, and cristobalite, wherein: the sialon material comprises a β-sialon phase, a glass phase, and optionally an α-sialon phase; the sialon material may contain the α-sialon phase, provided that the weight percentage of the α-sialon phase falls within a range of less than 15% based on the total weight of the α-sialon phase and β-sialon phase; and the area percentage, the glass phase appearing in a cross-section of the sialon material accounts for, is 6-10%. A method for producing the sialon material using the improving method, and a tool are also provided.SELECTED DRAWING: None
