- nanosized alpha alumina powder;
The present paper deals with an idea of introducing in a powder subjected to severe comminution a certain substance referred to as «grinding catalyst». It must be inert to aluminum oxide and provides mechanical barrier between crystallites, thus preventing them from coalescence. The elimination of this substance from the resulting powder should destroy the aggregates and lead to the powder composed of separate crystallites. The properties of the resulting powder with respect to green body formation and sintering into a dense material has been studied.
Additionally it has been shown that nanopowder produced can be used as a seed material to reduce γα transformation temperature and to get pure and fine alumina.
