| 摘要 |
The present invention relates to an apparatus for controlling a trace of elements in low melting metal by using multiple heat sources, comprising: a tube forming an internal vacant space to house target metal; a boat positioned within the tube and putting the target metal therein; a plurality of heating units locally heating the target metal within the tube to make a plurality of molten zones which are in a liquid state; a moving unit moving the heating units in the longitudinal direction of the tube; and a cooling unit cooling the target metal to make zones, except the molten zones in the target metal, crystal zones, wherein a trace of elements contained in the target metal is assembled in the molten zones and, as the heating units move, the trace elements are concentrated in one side end of the target metal and eliminated, thereby being capable of applying a high purity refinement process to the low melting metal and reducing a process time as the heating units are plurally equipped. |
