Abstract
Apparatus for producing molybdenum metal Apparatus includes a furnace that defines at least two heating zones of substantially equal length, the furnace maintaining each of the two heating zones at temperatures not greater than about 1200.degree. C.; a supply of precursor material; a process tube extending through each of the two heating zones of the furnace, wherein the precursor material is introduced into the process tube and moved through the two heating zones of the furnace; a pressure regulator operatively associated with the process tube to maintain an interior region of the process tube at a substantially constant pressure greater than an ambient pressure; and a supply of process gas operatively associated with the process tube, whereby the process gas is introduced into the process tube such that the process gas reacts with the precursor material within the furnace to form the molybdenum metal.
