Abstract

The results of the heterophase interaction of refractory-phase nanoparticles of Al₂O₃, ZrO₂, and HfO₂ with cobalt melts containing harmful impurities of nonferrous metals (tin and antimony) are investigated and summarized. It is shown that after the introduction of nanoparticles in the Co–Sn and Co–Sb systems, the degree of impurity removal, depending on the isothermal holding time, was 13–31 and 10–26 rel. %, respectively. It is found that the redistribution of impurities with nanoparticles in the melt in the form of ensembles and their removal to the phase boundary Me–gas/slag/ceramics can be represented as a two-stage process.

钴熔体中外源难熔相纳米颗粒与锡、锑的相互作用研究

研究并总结了耐火相纳米颗粒Al2O3、ZrO2和HfO2与含有害杂质的有色金属（锡和锑）钴熔体异相相互作用的结果。结果表明，在Co-Sn和Co-Sb体系中引入纳米粒子后，杂质去除率分别为13-31和10-26雷尔%，取决于等温保温时间。研究发现，纳米颗粒杂质在熔体中以系综的形式重新分布并移至相界Me-gas /渣/陶瓷的过程可表示为两个阶段。
