Abstract:

The program objective was to develop a process suitable for production of continuous aluminum oxide filaments at high rates by chemical vapor deposition. Several processes were investigated including gas phase hydrolysis or oxidation of AlCl3 and decomposition of organo-aluminum compounds both high and low pressure deposition regimes as well as immersion in boiling liquid were investigated. Production of alpha-alumina filaments by chemical vapor deposition was achieved in some cases producing dense, small grained filaments however, even the best appearing filaments had low strengths.
