It was found experimentally that on the initial part of crystal the fluctuations with amplitude more
than 1 mm leads to break of the capillary column melt and close of growth. The physical significance of this
functional relationship for this probably lies in the different orientation of surface tension forces. Regar d-less of the direction of stretching and an amplitude -frequency characteristics of development process of the
power of the octahedral facets increased with increasing growth rate. Accidents on existing ideas are the
result of periodic growth, due, for example, the rotation of the crystal in an asymmetric thermal field.
When carrying out the method of crystal growth with perturbations at the interface it to a solid phase, the
lateral surface is also composed of corrugations distinguishable to the naked eye.In general, the study of
structural defects in the crystals obtained in exacting heat conditions, showed that in this case, low-frequency disturbance of the melt at the interface reduces the average density of dislocations due to the
periodic melting of crystallization and partially “heal" the defective portions of the crystals.
