Abstract

Several compositions are investigated in order to determine the essence of the phase transformations occurring at temperatures up to 1600°C in the ZrO2 — Ln2O3 (Ln is Nd, Y, Yb) — Al2O3 — SiO2 (Fe2O3, TiO2) systems. The efficiency of using Y2O3 and Yb2O3 to stabilize cubic ZrO2 in the presence of a mixture of Al2O3 and SiO2 (Fe2O3, TiO2) is shown. Data show the possibility of fabricating high-quality zirconium-corundum articles with any proportion of Al2O3 and ZrO2.
