The mechanical activation influence on the habit of alumina lattice

Olga Yushkova

Abstract


The effect of mechanical activation (MA) 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.
