dc.description.abstract-enThis paper presents limiting values of equilibrium distribution coefficients of the admixtures in precious metals Ru, Rh, Pd, Os, Ir, Pt, Ag, Au and the periodical correlation dependences of the distribution coefficients on the proton number of admixtures. The presented values of ko and correlative relations give a possibility: - to determine the unknown ko values and to predict the behaviour of admixtures during crystallization processes, - to estimate the practical realization of zone melting or directional crystallization of various basic substances to choose suitable materials for those processes and to predict the refining grade, - to prognose the distribution ability and enriching of foreign admixtures with ko > 1 on the dendritic axis and accumulation of admixtures with ko < 1 in the interdendritic spaces in mother melt during dendritic segregation which always accompanies the solidification of substances.en
