Abstract:

The Czochralski technique has been developed or growth of single aluminum oxide in plate form for transparent armor application. A DESCRIPTION OF THE GROWTH PROCESS IS GIVEN ALONG WITH THE DEVELOPMENT WORK CARRIED OUT PRIOR TO ISSUANCE OF THE CONTRACT. Scale-up has been carried out to produce a single crystal plate with dimensions in the as- grown state of 46 x 66 x 386 thick. The problems of furnace design and power control for the larger size growth unit is described along with a preliminary amount of the optical quality. Author-PL
