Abstract
The thermodynamic modeling of interaction of yttrium ceramic with Nb–Si based molten alloys alloyed with Ti, Cr, Hf, Al has been performed. Formation of solid HfO2 oxide is shown to be the result of such interaction, and other elements are not involved practically in the chemical interaction. It is found in the course of modeling that yttrium reduction due to ceramic dissolution in the molten metallic solution is the main mechanism of interaction. The Y content in the solution depends on the temperature, metallic phase composition, and quantity.
