Effect of Adding Y₂O₃ on Synthesis of Al₄SiC₄ Powders

Abstract:

The reaction process of synthesis of Al₄SiC₄ from Al, Si and graphite powders and the effects of Y₂O₃ on synthesis and microstructure of Al₄SiC₄ were investigated in this paper. The results show that no substantial changes in the formation of Al₄SiC₄ content with or without addition of Y₂O₃. The addition of Y₂O₃ to Al, Si and carbon powder mixtures was found to be effective for obtaining tabular grains of Al₄SiC₄. Conversely, Al₄SiC₄ grains existed as irregular granules without addition of Y₂O₃.
