Abstract:

The physicochemical properties of Y2O3 and Al2O3 nanopowders produced by the laser synthesis were studied. Carbonate and nitro groups along with bound water are formed on the surface of the Y2O3 nanopowders, whereas only nitro groups are formed in the case of Al2O3. After calcination of the nanopowders at temperatures higher than 750 degrees C in air followed by cooling to room temperature, the nanopowders repeatedly sorb H2O and CO2. The influence of commercial dispersant Dolapix CE64 on the stabilization of aqueous dispersions of the Y2O3 and Al2O3 nanopowders was studied. The obtained results can be used in colloidal methods of compacting optical ceramics.
