Abstract
A method for obtaining high purity titanium by thermal decomposition of titanium iodides is provided which enhances productivity and improves the temperature control of the deposition substrate used, wherein crude titanium is charged into a reactor and a titanium tube is inserted therein. The titanium tube is indirectly heated by a heater while the interior of the titanium tube is evacuated independent of the inside of the reactor. Subsequent feeding of titanium tetraiodide into the reactor, while heating the tube from the inner or outer surface provides high purity titanium deposited on the other surface of the titanium tube.
