Abstract
Using various versions of mechanochemical synthesis for the preparation of nanodisperse particles of oxide materials is considered. The results of investigations of some solid-phase reactions in mixtures of reagents subjected to mechanical activation and subsequent thermal treatment are presented. The role of the salt matrix in preventing aggregation of ultradisperse particles has been studied. The efficiency of soft mechanochemical synthesis is compared with that of the sol-gel method. Both methods make it possible to obtain nanodisperse particles close in size.
