Summary:The heterophase interaction of exogenous refractory-phase Al 2 O 3 nanoparticles with cobalt melts containing nonferrous metal impurities, namely, tin and antimony, are studied. As follows from thermodynamic calculations and an analysis of possible versions of their removal from a melt, the probability of removing tin and antimony under melting conditions is low. The introduction of Al 2 O 3 nanoparticles into model Co–Sn and Co–Sb alloys leads to a decrease in the content of both tin and antimony. It was up to 30 rel % Sn and up to 26 rel % Sb depending on the melt holding time after the introduction of nanoparticles.
