The hydrothermal method of preparation of zirconia nanopowders was reviewed with respect to the influence of solution pH, mineralizer and TiO2 concentration on the composition and morphology of zirconia crystallite phase. The pH dependence of both the ratio of the needle-shaped monoclinic to oval tetragonal zirconia nano-crystallites and CaO concentration in the zirconia solution has been described. Compressibility improvement and sinterability deterioration of zirconia nanopowders due to the presence of needle-shaped crystallites have been shown. Hydrothermal crystallisation of zirconia nanopowders with a mineralizer-dependent amount of the tetragonal and monoclinic zirconia polymorphs composed of oval and elongated crystallites with various ratios or plate-shaped crystallites has been discussed. The effect of TiO2 on hindered hydrothermal crystallisation of zirconia solid solutions was shown. A potential of the in-situ method for shaping the nano-structure of the TiC/ZrO2 composites has been presented. A slight effect of the carbon precursor and a significant one of the carbon incorporation way on the morphology of TiC in-situ inclusions have been documented.
