We studied correlation between the sizes of crystallite and resistance ZrO2 at the pressures 22 - 50 GPa and temperatures 77 - 400 K. Nanocrystalline praseodymium doped zirconia powders were produced using a microwave driven hydrothermal process under pressures up to 8 GPa. Nanopowders of zirconia with Pr in solid solutions having Pr contents of 0.5 mol %. The bulk material sample of zirconia having Y2O3 contents of 5 mol %. Size of crystallites changed from 10 to 500 nm.
