New Techniques are presented for the determination of the capillary constant and the coefficient of thermal expansion of the melt using an electrocontact sensor (ECS). The density of the melt, the capillary constant, the coefficient of the thermal expansion of the melt, the growth angle, and the characteristic time of thermal relaxation of the thermal zone are determined for the case of growing the lithium niobate crystals by Czochalski technique.
