Synthesis of Al2O3/SiC composites by the SHS microwave heating process
- 77 Downloads
Alumina/silicon carbide composites were synthesized by the microwave induced SHS (Self-propagating High-temperature Synthesis) process. SiO2/Al/C powders were used as starting materials and samples were ignited by using a 2.45 GHz multimode home microwave oven (700W). Effects of the mixing ratio of SiO2/Al/C powders, reaction environments, and weight percent of KNO3 as a reaction promoter on the formation of the final product were studied.
