摘要：Behavior of phosphorus, aluminum and calcium in metallurgical grade silicon has been investigated during electron beam melting with melting time modified. The results showed that the content of phosphorus, aluminum and calcium gradually decreased with time passing, and the lowest content of these impurities were 2.2 10-5wt% P, 8.5 10-5 wt% Al and 1.5 10-4 wt% Ca respectively. The removal rates of these elements were expressed by the first order equation. Rate constants for phosphorus, aluminum and calcium were 0.11, 0.12, 0.13 min-1 respectively.
