Popis:	The composite samples using flint clay, andalusite and silicon carbide as starting material are made from the proportion of 35:60:5, 45:50:5, 55:40:5, 65:30:5 respectively. The samples are sintered at 1200°C,1300°C,1400°C,1450°C and 1500°C holding 4hrs separately. Both microstructure and mechanism of oxidation were analyzed by XRD and SEM. The results show that the samples have good resistance against oxidization below 1500°C, only the sample of fourth formula perform excellent and have the thinnest oxidation layer between all the formulas at 1500°C.
