One of the methods to prevent the oxidation of silicon carbide (SiC) is to coat it with Al2O3 which has high thermal stability. In this study, the properties of Al2O3 coated SiC composite powders were examined to prevent the oxidation of SiC particles by developing a thermal barrier coating and it is aimed to contribute for reducing the gases which make a greenhouse effect and cause global
