Abstract

Abstract In this experiment, directional solidification method was used to prepare metallurgical grade silicon ingot. We have studied the solidification rate which influenced the results of the experiment. Experimental results showed that the impurities were concentrated mostly in the top of silicon ingot. It was inferred that second or more times directional solidification experiments is needed to remove the impurities. What’s more, it showed that the best solidification rate is 1.5mm/min in this study.
