Abstract:

A process of reduction of boron chloride by hydrogen is given which can be expediently conducted in a glow discharge during pressure from 30 to 200 mm Hg. The formation of elementary boron both in highly dispersed state and also in the form of growths on electrodes depends upon the kinetic and electrical conditions of the process. Laboratory production of highly dispersed boron with purity up to 99.9 and yield to 50 from boron chloride in a glow discharge is possible with a single passage of the gas mixture through the discharge. According to the data of comparative x-ray investigations of elementary boron obtained by different methods, electrodischarge boron is the purest and the most typical sample of microcrystalline boron.
