Processes of forming amorphous boron-carbon alloy in bulk form without crystallization are disclosed. Such products can be produced in thicknesses well in excess of ten mils by employing Reynolds number gas reactant flow conditions of 40 to 120. The resultant products of such processes having grain sizes preferably less than 30 A are also disclosed.

A process of forming amorphous boron-carbon alloy in bulk form comprising: subjecting a releasable mold reaction surface to a gaseous mixture of at least one boron-containing gas, at least one carbon-containing gas, and a reducing gas, at temperatures of 950°C. to 1300°C., and Reynolds Number flow condition of 40-120, until an amorphous boron-carbon alloy structure at least 40 mils thick is deposited on the mold reaction surface, and removing the formed structure from the mold reaction surface.
