Аннотация Features crystal growth method “synthesis-solute-diffusion”when applied ultrasonic field are considered. Dependence of the crystal optical transmission heterogeneity frequency ultrasonic vibrations determined. System Tests showed that the optimal vibration frequency that provided a homogeneous crystals and permitting the maintenance of the solidification front in a predetermined position with an accuracy of ± 5 % frequency is 4 MHz ± 5. Comparison of the optimum frequency ultrasonic vibrations to increase uniformity in the mode of crystals convective transport under the Czochralski method and conditions of diffusive transfer method indicates a significant difference between these frequencies, i.e. character determines the transfer conditions of optimization process.
