Abstract
Pyrolytic tungsten coatings were deposited onto the surface of sol microspheres with tungsten hexacarbonyl used as precursor. A method was developed for reduction of germanium tetrachloride in the presence of a catalyst based on sol microspheres coated with pyrolytic tungsten. The method makes it possible to reduce the process temperature and diminish the number of stages in production of germanium. The kinetic characteristics of the catalytic reduction of germanium tetrachloride with hydrogen were determined.
