titanium processing
High-purity (99.999 percent) titanium metal.
In 1925, Dutch scientists A.E. van Arkel and J.H. de Boer successfully produced ductile titanium by dissociating titanium tetraiodide on a hot filament within an evacuated glass bulb. This method allowed for the creation of metal with significant ductility, marking a notable advancement in titanium processing during the early 20th century.1
