Abstract

PURPOSE: A melter for floating zone process that heats the floating zone by the light concentration method is contained in a high-pressure vessel to make it possible to apply the floating zone method to an insulating material of high melting point and volatile substance under elevated pressure.
CONSTITUTION: A melter 10 for floating zone process that is provided with the starting rod and the seed rod both of which are held with holders on each one end in the sample chamber covered with a cylindrical quartz tube 3 is set on the support 7 and the cover for pressure vessel 8 is moved and tightened with the screw 9. Then, a pressurizing gas is sent through a pressure booster to adjust the pressure to a prescribed one and light is concentrated from the heat source lamp 2 to the center to melt the starting rod 4. At the same time, the starting rod 4 is made to revolve by the driving mechanism 11 to form the floating zone and moved downward under these conditions to effect the growth of single crystal.
