Aluminum Oxide - an overview | ScienceDirect Topics
Aluminum Oxide Aluminum oxide (Al2O3) is most often prepared from AlBr3, AlCl3, trimethyl-aluminum (TMA), or trimethyl-amine alane (TMAA) precursors mixed with O2 or N2O [7, 76, 152, 153]. From: Handbook of Deposition Technologies for Films and Coatings (Third Edition), 2010
Alumina (Aluminium Oxide) - The Different Types of …
Tabular aluminum oxide is recrystallised or sintered α-alumina, so called because its morphology consists of large, 50-500 μm, flat tablet-shaped crystals of corundum. It is produced by pelletising, extruding, or pressing calcined alumina into shapes and then heating these shapes to a temperature just under their fusion point, 1700-1850ºC in shaft kilns.
