The aim of the investigation was to increase the reactivity of the starting γAl2O3 by mechanical treatment in two types of highenergy activators – vibratory disc mill and vibratory ball mill. In continuation, the decrease of the subsequent sintering temperature as well as the treatment duration would be induced by making the transition into final thermostable αAl2O3 modification easier and .

Our 8000 series Mixers/Mills® are highenergy ball mills that pulverize samples by shaking one or two sample vials with grinding balls, in a figureeight motion, several hundred times a minute! Typical samples include hard or brittle samples such as rocks, minerals, cements, and ceramics.

Apr 29, 2011· Nanoparticles of zinc oxide (ZnO) are increasingly recognized for their utility in biological applications. In this study, the highenergy ball milling (HEBM) technique was used to produce nanoparticles of ZnO from its microcrystalline powder. Four samples were ball milled for 2, 10, 20, and 50 hours, respectively.

Al2O3) were milled separately in the highenergy planetary ball mill up to 20 h in the air. Milling in the air of prealloyed copper powder promoted formation of fine dispersed Al2O3 particles by internal oxidation. Hotpressing was used for compaction (800 0C for 3 h in argon at pressure of 35 MPa).
