Abstract
In this work the yttrium-aluminate glasses with different composition A60Y40M (76.8 mol.% Al2O3), A63Y37M (81.8 mol.% Al2O3), and YAG (62.6 mol.% Al2O3) were prepared by flame synthesis in the form of glass microspheres and characterized by OM, SEM, XRD, HT XRD and DSC analysis. On the basis of the results of HT XRD and DSC analysis, the individual crystallisation experiments were performed. The morphology of crystallized microspheres was studied by SEM and the content of individual crystalline phases was evaluated. The microspheres with the eutectic composition A60Y40M were hot-pressed in vacuum under various conditions (temperatures 900-1600°C, pressure 80 MPa, isothermal dwell time 0-30 min). The highest hardness 17.7 GPa and fine grained microstructure was observed for the samples hot pressed at 1300°C with isothermall dwell time of 30 min.
