The distribution of aluminum in the ingot was found that aluminum was dragged from the bottom to the top and from the edge to the center of the ingot. The aluminum content in the edge was the lowest, even lower than the detection limit (1×10−5%) of ICP–AES. The evaporation of aluminum during EBM process was studied both theoretically and experimentally. The relationship between the removal efficiency for aluminum and the surface temperature of the melting silicon and melting time was deduced from Langmuir’s equation and Henry law. It showed that the removal efficiency of impurity aluminum increased with the increase of the melting time and the surface temperature of the melting silicon. Good agreement was found between the calculated value and the measured value.
