- The results on the ZrO2–FeO system studies in a neutral atmosphere are presented. The refined eutectic point has beenfound to correspond to a ZrO2 concentration of 10.3 ± 0.6 mol% at 1332 ± 5 C. The ultimate solubility of iron oxide inzirconia has been determined in a broad temperature range, taking into account the ZrO2 polymorphism. A phase diagramof the pseudobinary system in question has been constructed.

- We present the results of the investigation of the ZrO2-FeO system under an inert atmosphere. We have refined the position of the eutectic point, which lies at 1332 +/- 5 degrees C and 10.3 +/- 0.6 mol % ZrO2. The iron oxide solubility boundaries in zirconium dioxide have been determined over a wide temperature range taking into account the polymorphism in ZrO2. A phase diagram for the system has been designed.

- —The morphology of the crystalline phases prepared at different cooling rates, temperatures, andcompositions of melts in the ZrO2–Al2O3system is investigated. It is established that both the quenched andslowly crystallized samples containing 35–70 wt % ZrO2have a submicron structure. Outside this concentrationrange, the ingots have a zonal structure: the peripheral region is formed by large baddeleyite crystals (at a ZrO2content higher than 70 wt %) or corundum crystals (at a ZrO2content lower than 30 wt %). This character ofthe crystallization confirms the presence of the phase separation (liquid immiscibility) region in melts of thissystem. A variant is proposed for the phase diagram of the system under investigation.
