Kyropoulos technique

Facilities of the ROST type (Fig. 14.2) are also adapted for the modified Kyropoulos technique (with a changeable level of the melt in the crucible) and the automated continuous growth method (with constant melt level) in its two versions for crystal puUirig continuous and discrete.

The methods of seed-crystal pulling from the melt (the Kyropoulos and Czochral-ski techniques) have a number of inherent merits as compared to the normal crystallization in a crucible. First, there is the possibility of rotation of the crystal pulled that provides for intensive mixing of the melt before the crystaUization front Secondly, there are no problems associated with crystal adhesion. But, at the same time, these methods are very sophisticated from the technical standpoint...
