Abstract
Al2OC–SiC composites were synthesized using a mixture of α–alumina, silica, carbon black and magnesium oxide as the starting materials. The effects of heating temperature and MgO addition on Al2OC–SiC composites formation were investigated. The results showed that Al4O4C formed as intermediate product when the batch mixture was heated in argon atmosphere, and MgO addition accelerated the synthesis reaction for Al2OC–SiC composites. The synthesized powders consisted of plate-like Al2OC and whisker-like SiC. The oxidation characteristics of Al2OC–SiC composites was measured by TG method. |
