ABSTRACT:
The subject matter of the present invention relates to a method of producing crystals of materials for use in the electronic industry. The method provides for growing a crystal from a liquid phase in apparatus for monocrystallization with the use of additional apparatus situated inside a chamber for monocrystallization. The additional apparatus includes inter-chamber manipulators (6) and (7), which aid in carrying out in one crystallization process the multiplication thereof by the use of more than one or many crystal seeds placed in the monocrystallization chamber, whereby a change in the location of seeds (4) and or (9) and or (11) is effected by the manipulators (6) and or (7) controlled from outside of the pressure chamber (1) and by utilization of catches (14) installed inside the pressure chamber (1).
