【 摘 要 】

In this paper, a technique for non-conductive silicon heating and conductive silicon levitation is described. This research focuses on studying the effect of applied power on temperature of droplets during phosphorus removal from Silicon and ferrosilicon alloys (24%Fe- 76%Si) by utilizing a refining process known as electromagnetic levitation with subjecting the levitated alloy to an argon-hydrogen gas flow. The effects applied power on temperature were observed and analyzed. The results of this investigation will use vacuum electromagnetic levitation technology solar grade silicon samples will be prepared from relative inexpensive raw material, metallurgical grade silicon.
