摘要
Abstract: We isolated Al2O3–Y2O3 powders using two different methods: filtration and nanospray drying. The obtained samples were investigated using thermogravimetry, differential scanning calorimetry, X-ray phase analysis, BET, and scanning electron microscopy. We examined the processes of linear shrinkage during thermal and compression consolidation using field-assisted sintering. A comparative analysis of the powders obtained by the two methods was conducted and the results are presented and discussed. A powder containing 96 vol % of the Y3Al5O12 phase can be produced through calcination of the precursor obtained by nanospray drying at 1100°C for 10 min. © Pleiades Publishing, Ltd. 2022.
