A high-rate synthesis ofnano-crystal zirconium oxide of tetragonal modification is performed by activation of amorphous zirconium hydroxide in mechano-chemical apparatus. Preliminary short-time mechano-chemical treatment of the hydroxide also allows one to decrease substantially (by 150-200

The corrosion stability of finely dispersed iron powder obtained by grinding in heptane and in heptane with a surfactant added (oleinic acid) in a 0.85 % NaCl solution at a temperature of 37 ?C is investigated. It is shown that corrosion stability increases with increasing grinding time; it also increases in the presence of the surfactants (SAS), in spite of the increase of powder dispersivity. The increase of corrosion stability is connected with the formation of a thin (up to 10 nm thick) protective surface layer containing graphite-like and oxide layers, as well as complex organic compounds. The composition and structure of these layers depend on grinding time and on the presence of SAS.

The mechanochemical method of active aluminium preparation was developed. Also technique of preparation of aluminiumorganic derivatives from unsaturated hydrocarbons is fulfielled. Possibility of realization of hydroalumination under the conditions of mechanochemical activation in drums of planetary mills was demonstrated for the first time. Butillithium via reaction of a butenes mixture with a lithium hydride in conditions of a mechanochemical activation was synthesized.

An equimolar ZnO and Cr₂O₃ powder mixture was mechanically activated by grinding using a high-energy vibrational mill for 0-180 min. Structural changes of the material that occur during mechanical treatment were analyzed using the surface characterization method (specific surface area, and based on the latter the calculated mean particle size) and X-ray diffraction line broadening theory. The characteristic temperatures within in the temperature range of 20-1100

The phenomenon of mechanical impact has been studied to determine the response of solids to the intensive mechanical disturbance.  The process of blow is considered as sudden simultaneous change of velocities of all atoms of striking particle. The probabilities of lattice excitation and prerequisites to structural imperfections have been investigated. The calculations for cubic germanium, silicon, and diamond crystals were performed.

The investigation of phase composition in Y₂O₃-Ta₂O₅ and La₂O₃-Ta₂O₅ systems is carried out at mechanical activation and subsequent heat treatment. In Y₂O₃-Ta₂O₅ system the interaction of components is observed during mechanical activation. Heating of mechanically activated intermixtures of oxides leads to the formation of orthotantalates of yttrium and lanthanum. Temperature and time of complete interaction of components is much less than in a traditional ceramic method. The new convenient method of synthesis of tantalates of rare-earth metals is developed.

The influence of mechanical activation on synthesis processes and magnetic properties of hexagonal ferromagnetics of the structural type W has been studied. It is shown that in case of mechanical activation after preliminary annealing the optimal synthesis temperature reduces by 80-100

The effect of mechanical activation on high-temperature synthesis in the regime of thermal explosion in Fe

The effect of the preliminary mechanical treatment of metal powders on the quality of coatings obtained by plasma deposition is investigated. Substantial improvement of the inner structure and strength properties of the coatings is demonstrated. It is stated that the specific heat effect of the interaction of mechanically treated copper powder with acetic acid increases for mechanical treatment up to 15 min, which is likely to be due to the accumulation of defects in metal volume. The chemical reactivity of the mechanically activated copper powder and of the copper powder obtained by means of the electric explosion of wires is demonstrated to correlate with interplane distances between the planes with (111) Miller indices.

Results of systematic studies of framework zirconium phosphates synthesis via  mechanical activation (MA) of the mixture of solid salts followed by the hydrothermal treatment (HTT) in the presence of surfactants, drying and calcination in air are considered. Application of modern physical methods sensitive to the state of bulk and surface of nano-systems (XPD, SAXS, TEM, EXAFS, FTIRS, SIMS, UV-vis) allowed to elucidate genesis of those complex systems containing different stabilizing/modifying cations and anions. The local structure of zirconium phosphate nuclei formed in the course of MA and spatial distribution of guest cations within those nanoparticles strongly depend on the composition of starting solid reagents, which determines a mode of the acid-base interaction in the activated mixture. These properties determine in turn realization of different mechanisms of complex framework phosphates crystallization under HTT - either via oriented stacking of primary particles (occurs even in neutral or alkaline solutions) or by dissolution-precipitation route in acid solutions. Factors determining the structural type, thermal stability, surface composition and solubility of crystalline complex zirconium phosphates prepared via MA route were elucidated and analyzed as dependent upon the composition and genesis of those systems.
