July 2007; accepted 10 September 2007 Abstract: The microstructures and properties of Cu-8.0Ni-1.8Si alloy subjected to different heat treatments were examined by mechanical and electrical......
at the bottom of the Al-Si alloy along the direction of super gravity. Then the refined silicon was collected by aqua regia leaching. The purity of the collected silicon is analyzed as 99.92%, which..., and later the refined silicon is recovered by super gravity. Al-Si alloy is a typically binary eutectic system. Alloying MG-Si with Al is a process of redistribution of impurities in silicon by taking......
