Influence of AlF3 and hydrothermal conditions on morphologies of α-Al2O3
Abstract
Homogeneous α-Al2O3 platelets were synthesized by introducing AlF3 to alumina precursor. The effects of AlF3 additive on the phase transformation and morphology of the prepared α-Al2O3 platelets were investigated. The results show that a single phase of α-Al2O3 with an average particle size of 8 μm can be obtained at 900 °C with 2% AlF3 additive. The transformation temperature decreasing is attributed to introduction of Al3+ vacancy and to the …
