摘要：In order to refine metallurgical grade silicon at low temperature, boron
   removal from Al-Si alloy at 1200 °Cwas investigated by using
   Na_3AlF_6-Al_2O_3 slag. The results show that the slag-making refining
   process can obviously improve the removal effect of the boron from the
   Al-Si alloy. Under the same melting time, impurity boron content in
   primary silicon is reduced to 2.85*10~(-6) after refining slag of Al-Si
   alloy. The removal effect of the boron is increased by 15.7% compared
   with the sample without the treatment of slag-making refining. Moreover,
   the removal effect of impurities in primary silicon crystal gradually
   increases with the prolonging of slag-making refining time.
