| Available methods of cryochemical treatment for nanopowders and nanoceramics production were briefly described. The basics and theory of freeze-drying were discussed. Recent achievements and efforts in this field have been summarized. The proper choice of cryochemical treatment methods appeared to be the enough easy route for producing nanosized ceramic powders with high dispersity and desired structure of agglomerated particles. Morphology and structure of stabilized zirconia precursors obtained via different cryochemical treatment techniques has been investigated in details. It was shown that physical and chemical properties of final powders (such as mechanisms of phase formation, agglomeration degree, etc.) as well as the kinetics of it crystallization strongly depend on the way of it initial treatment. |
