Abstract
An effect of conditions of hyperfine grinding on the size of crystallites and on the aggregation degree of received a-Al2O3 nanopowders has been examined. It has been demonstrated that the average size of crystallites of a mechanically grinded powder is a function of relative humidity in the barrels of a planetary mill with a pronounced minimum (200
