Non-Isothermal Method for Charactering the Oxidation Resistance Property of SiAlON Materials

Article Preview

Abstract:

The oxidation resistance of SiAlONs is one important property. In our work we present a test method to characterize its anti-oxidation property with the non-isothermal oxidation process using Thermo Gravimetric Analyzer (TGA). The oxidation starting temperature (Ts), maximum oxidation rate temperature (Tm) and the value of the oxidation weight gain per unit area (Ga) are three key parameters to describe the antioxidant properties of the material. Experimental results prove this test method is easy and reasonable and it will be developed as the national standard of China.
