Abstract
For the thermal dissociation of titanium tetraiodide to produce metallic titanium (see Group II), the traiodide is produced by passing gaseous iodine into contact with titanium-bearing material at a temperature above the boiling point of the tetraiodide. The gaseous product thus formed is either fractionally cooled, or fractionally distilled (preferably at 150 DEG C to 379 DEG C at a reduced pressure) to recover the pure tetraiodide. The iodine liberated from the dissociated tetraiodide is recycled. Specifications 662,577, 662,579, 698,233, 698,234, 698,235 and 698,236, [Group II], are referred to.ALSO:Pure titanium is produced by passing a preformed gaseous product consisting essentially of titanium tetraiodide into contact with a surface heated to a temperature in the range of 1100 DEG C-1700 DEG C. The deposition surface may be of tungsten or titanium. The tetraiodide is preferably formed by passing gaseous iodine into contact with titanium-bearing material at a temperature above the boiling point of the tetraiodide. The gaseous product thus formed is either fractionally cooled, or fractionally distilled to recover the pure tetraiodide. The liberated iodine is recycled. Specifications 662,577, 662,579, [both in Group III], 698,233, 698,234, 698,235 and 698,236 are referred to.
