Abstract
Melting and dispersion of oxide materials in the system ZrO2 - HfO2 - Y2O3 is carried out in furnaces with concentrated radiant and induction heating. The polyfractional powders obtained are stabilized solid solutions of the fluorite type. A reduction is established for elementary cell parameters (from 0.5144 to 0.5127 nm) for specimens whose composition relates to an isoconcentrate with 10 mole% Y2O3 with an increase in HfO2 content. Melted and dispersed ZrO2 - HfO2 - Y2O3 materials are promising for creating dense and highly refractory ceramic materials.
