Ductile titanium of high purity is produced by decomposing titanium iodides, formed by the action of iodine vapor upon the crude metal, on a hot filament. The construction and operation of glass units producing 300 to 600 grams of titanium per run in the form of rods of 0.3–0.4 inch diameter are described. This metal has a hardness of about 90 Vickers as deposited, and it can be cold worked drastically by swaging or rolling. Working and mechanical properties have been investigated.
