Abstract

The results of research carried out in the Institute of High Pressure Physics in collaboration with partners within COST action D30 and D32 is presented. The main results are highlighted:

microwave driven hydrothermal synthesis is well suited for synthesis of doped nanopowders

  • doping on nanopowders is an effective tool to reach high doping levels
  • it seems that hydrothermal synthesis permits to reach high doping levels
  • new phenomena have been discovered as far as optical properties of the nanopowders.
  • application of high pressure permitted to obtain dense transparent nanoceramics of YAG
  • new methods of nanopowders characterization have been developed:
  • measurements of density of nanopowders
  • measurement of grain size distribution with the use of fine analysis of x-ray diffraction profiles and determination of lattice constants of nanopowders
