| 英文摘要 | Al-Si solvent refining is a promising process for silicon purification, and the key impurity elements are boron and phosphorus. Thermodynamic calculation and experiments in particular temperatures show that boron and phosphorus segregation coefficients in Al-Si melt decrease with decreasing temperature, and it is not verified in traditional solidification. In order to character boron and phosphorus removal in Al-Si solidification over a temperature range, high purity hypereutectic Al-Si melts were solidified at relatively low cooling rate. It is found that boron and phosphorus removal rates increase with decreasing temperature. The tread that the boron and phosphorus segregation coefficients in the Al-Si melt decease with decreasing temperature is confirmed in solidification over a temperature range. In addition, aluminum content in purified silicon is close to the maximum solid solubility of aluminum in silicon.
