The mechanical activation influence on the habit of alumina lattice

The effect of mechanical activation of alumina on its physical and mechanical properties has been studied. It was shown that spontaneous aggregation of particles of activated alumina suppress dusting. Distribution of particles primary and mechanoactivated alumina after measurement granulometric size composition on laser graininess meter « Мicrosizer – 201C» is shown and difference of particles distribution of is established. Distribution of particles of alumina after mechanical activation in planetary mill М-3 is presented by three areas. The explanation of the mechanism of distribution as a result of crystals variation of alumina is perofrmed.
