POSSIBILITIES OF EXCHANGE MECHANOCHEMICAL REACTIONS FOR PREPARATION OF DISPERSE CERAMIC MATERIALS

摘要

Exchange reactions proceeding under the conditions of mechanical activation are widely used to obtain nanometer-sized particles of oxides and oxide materials. The synthesis process includes the interaction of salts of different metals. The salts which formed during the synthesis, are the matrices preventing the particles of the target reaction oxides from aggregation. The target products and initial products tracers are separated from the matrices by dissolving them in water, ethanol and other solvents. The goal of the present work is to establish the possibilities of solid-phase exchange reactions for obtaining dispersed silicates of aluminium, magnesium and solid solution ZrO_2-Y_2O_3, which are widely used in ceramic industry.
