摘要： A crystal growth apparatus is herein disclosed, which comprises a vertical magnetic field-generating apparatus for establishing a cylindrical, vertical magnetic field space; a vertical Bridgman furnace arranged within the space; a base plate positioned above the magnetic field-generating apparatus; a heat-generating furnace comprising a water jacket, a quartz tube and a heating element; a combustion tube for accommodating a crucible at a predetermined position; a means for vertically suspending and supporting the combustion tube; a means for guiding the suspending means to move it up and down; and a means for driving the suspending means in the upward and downward directions such that the combustion tube is lowered and risen in the heat-generating furnace; the guide means and the driving means being fitted to the base plate; the heat-generating furnace being arranged at a predetermined position within the space and fitted to the base plate through a supporting member; and a motor of the driving means being placed at a position wherein the motor is not greatly affected by a magnetic field established by the magnetic field-generating apparatus.
