Viscous flow spark plasma sintering of glass microspheres with YAG composition and high tendency to crystallization
Original language description
Present work is focused on the preparation of bulk glass with stoichiometric yttrium aluminium garnet (YAG) composition, which has high tendency to crystallize. Glass microspheres were prepared by flame synthesis from sol-gel prepared YAG precursor. Sintering conditions in SPS apparatus such as heating rate, pressure and temperature were optimized with the aim to prepare transparent material. Results revealed that glass with high tendency to crystallize is very sensitive to time of densification under load (associated with the maximum applied temperature). The increase of the pressure led to the expansion of the translucent part of the sample. Dense, and slightly translucent amorphous samples (total transmission measured at 550 nm was 4.8 %) were successfully prepared by viscous flow SPS sintering of glass microspheres at temperatures below 910 degrees C without any isothermal dwell.
