dc.description.abstract-enA systematic study is presented of equilibrium and liquidus curves of available binary systems A-M, where A are basic elements and M are admixtures, for 50 basic elements. The values of equilibrium distribution coefficients of admixtures k(oM)(A) in dilute solution in the range near the pure basic metals were calculated. The correlation curves of k(oM)vs. the atomic number were constructed. These correlations enable us to predict the unknown k(oM)(A). The different behaviour of admixtures with complete and incomplete d electron levels was shown. Two independent parabolic approximations describing the periodic dependence of k(oM)(A) on the atomic number of admixtures for the basic elements Si, Ge, Ti, Zr and Hf were investigated. There is a relatively good agreement between measured and calculated values of k(oM)(A). The probability of correct prediction of the unknown koMA for some admixtures has increased accordingly.en
