The paper presents the results of computer simulation of the process of growing Ві2Те3 based thermoelectric materials by vertical zone melting method. It was found that, depending on the velocity of the heater and coolers, not only the curvature of the crystallization front changes, but also its shape. At temperatures of the heater and coolers Th = 1058K, Th = 303K for velocities greater than 1.25 cm/h, the crystallization front along the entire crystal becomes convex into the solid phase, but at lower velocities it changes its shape from convex to concave along the grown sample.
