Abstract:

Two vapor deposition techniques were tried for the deposition of aluminum oxide filaments. Neither technique produced satisfactory deposits. Silicon carbide filaments were deposited from trichlorosilane and trichloromethylsilane. An x-ray analysis of silicon carbide and boron carbide was also completed. The presence of SiC and B4C was not shown conclusively. Metallographic examinations were made on all filament materials. The titanium compounds showed a crystalline structure while no crystal structure was evident on the other materials. Author
