Abstract : This report describes the structure of boron filaments vapor-deposited at approximately 1000 C on a tungsten wire substrate. Production and specially prepared filaments were examined as were samples taken from the deposition chambers after a filament length was cooled there in place. Both the morphology and crystallographic structure of boron filaments are described.
