Investigation of the coexistence curve shape in insulating liquids and conducting alloys by the method of phase separation boundary's movement

摘要

The method of phase separation boundary's movement is proposed for the critical phenomena studies in systems with a miscibility gap. The applicability of the method to investigation of liquid---vapour and liquid --- liquid phase transitions both in insulating liquids and conducting alloys is shown. Critical indices and critical amplitudes for C_2H_6 and F_3Cl_3C_2 as well as for the binary In - Te system are estimated.
