3 Terms and Definitions

The following terms and definitions apply to this document. 3.1 Nitrogen oxide material oxynitridematerials The Si, Al, Mg and other elements of nitride, oxide formed a solid solution ceramic materials, including sialon (SiAlON), Aaron (AlON), magnesium Aaron (MgAlON) series materials. 3.2 Oxidation resistance oxidationresistance The ability of a material to resist oxidation in an oxidizing atmosphere at a temperature of. Principle 4 In the high-temperature oxidizing atmosphere, nitrogen oxide material oxidation reaction occurs above a certain temperature, the quality will increase with temperature increase. With increasing temperature, the oxidation reaction rate to accelerate. When the surface is completely oxidized, and its quality is no longer increasing temperature Increases. By measuring the mass of the sample at a series of temperatures, can be plotted versus specimen quality and temperature, and then calculated by To oxidation weight gain per unit area of \u200b\u200bthe sample, the initial oxidation temperature, the maximum rate of oxidation temperature and other indicators used to characterize the oxidation resistance of the sample.

5 Test equipment and apparatus

5.1 Furnace Temperature zone temperature is less than or equal to 5 ℃, the highest temperature of greater than or equal to 1600 ℃. Having at least a gas line (at the bottom of the inlet, Top outlet), through the flow of 0.5L/min ~ 5L/min of gas. The furnace should be able to analyze samples Balances Real-time measurement.
