Abstract
High purity crystalline boron is produced by thermal splitting of a boron hydride or partially halogenated boron hydride wherein the boron compound with or without a reactive or non-reactive diluent gas, or wherein a boron halide compound in the presence of atomic or molecular hydrogen with or without a diluent gas, is brought in gaseous form into contact with a boron body at a temperature above the splitting temperature of the boron compound, the boron body being pre-heated until the temperature and conductivity are sufficient to allow further heating to reaction temperature by means of direct passage of current. The boron body may contain intentional impurities and may be of any desired shape. In a preferred method of operating, the boron compound is conducted through one or more nozzles which may be moving and/or additionally cooled, from which the boron compound flows directly on to the heated body. The reaction temperature is preferably above 1200 DEG C. to ensure crystalline deposit. The carrier gas preferably is one with poor thermal conductivity, e.g. argon, but may also be one with reducing properties, e.g. hydrogen.
