Abstract
PURPOSE: To simply and easily manufacture high quality large single crystal, by regulating the number of rotations of lifting shaft so as to keep the shape of solid- liquid interface nearly in flat face corresponding to the change of thermal enviromment accompanied by the development of crystal upbringing.
CONSTITUTION: Shape of the solid-liquid interface 4 is grown up keeping nearly in flat face by pulling up the single crystal 1 of B12SiO20 etc., especially giving suitable rotation to the axis 3 after contacting seed crystal attached to the lifting shaft 3 with the molten liquid 2. On this occasion, in regard to the most suitable number of rotations of lifting shaft ωc keeping the interface 4 at flat face, straight-line relation shown by the formula ωc=aK+b (a and b;experimentally found constant), is comfirmed between ωc and the aspect ratio K=H/D(H;height of the molten liquid, D; diameter of molten liquid) experimentally. That is, the formation of solid-liquid interface of the single crystal 1 is able to keep always flat maintaining the other factor nearly constant, by decreasing the number of rotations ωc of the shaft 3 and accordingly, high quality large single crystal having uniform characteristics, is able to manufacture easily.
