Abstract
Novel forms of molybdenum metal, and apparatus and methods for production thereof. Novel forms of molybdenum metal are preferably characterized by a surface area of substantially 2.5 m2/g. Novel forms of molybdenum metal are also preferably characterized by a relatively uniform size. Preferred embodiments of the invention may comprise heating a precursor material to a first temperature in the presence of a reducing gas, and increasing the first temperature at least once to reduce the precursor material and form the molybdenum metal product.
