Abstract

The theoretical foundations of the process of electric transfer (ET) in melts growing during contact melting (CM) of binary systems are considered. It is shown when the modes of this process will be carried out - speed-up and speed-down. It has been established that electro transfer makes an additional contribution to the magnitude of the rate of macroscopic flow (determined by the displacement of inert tags), due to the inequality of the partial diffusion coefficients of the melt components. The electric current passing through the liquid layer, formed by the CM, can have a very significant impact on the rate of its growth. Depending on the direction of the current, both increase and decrease in the speed of the CM can be observed. The paper also discusses the main regularities of the ET process at a CM, studies the effect on its parameters of the degree of difference in some physicochemical characteristics of the melt.
