Abstract:
The objective of this development program was to use the Bridgman process for the growth of single crystal aluminum oxide in plate form for transparent armor applications. A furnace design was established and testing was carried out on both power and control circuits. A number of growth runs were made to establish the correct operating conditions for crystal growth within a shaped crucible. Successful growth of good quality single crystals was achieved although more work is required to obtain large size under reproducible conditions. Author
