Abstract:
A single crystal material auxiliary melting apparatus for heating and melting a single crystal raw material in an auxiliary crucible and for supplying melt into a main crucible, said apparatus comprising:a conductive susceptor arranged around said auxiliary crucible so that it can be moved in a vertical direction; a coil wound around said susceptor and with high frequency current applied thereon; and means for moving said susceptor in such manner that heating of the raw material in said auxiliary crucible is started by arranging said susceptor at a high position on said auxiliary crucible and by heating said susceptor with secondary induction current, said susceptor is moved aside from said position on said auxiliary crucible after melting of said raw material has been started, and the raw material in said auxiliary crucible is heated by secondary induction current.
