Floating Zone Refining of Boron Using Electron Beam Melting,

Abstract

Boron rods, prepared by the reduction of boron trichloride with hydrogen, were refined by the floating zone process. The melting was accomplished by electron bombardment, using a 3000-v, 0.2 ampere beam. The band gap for a zone refined sample after three passes was 1.30 ev as determined from resistivity measurements. It was observed that carbon is an electrically active impurity, and that nickel and tungsten are not. (Author)
