Abstract
Described is a method and apparatus for producing high purity titanium and high purity titanium so produced. The process contemplates producing titanium sponge in a container and performing titanium fused salt electrolysis in situ in the same container to produce high purity titanium crystal, and where especially low oxygen content is desired, to treat the high purity titanium crystal as produced with iodine.
