Production of Titanium Metal
I do not know whether the Hunter Process with sodium is still used, however, as a chemistry student in the seventies I had a summer job in a plant (ICI Bain Works, Wilton site on Teesside) which did use this process. Because of the high reactivity of sodium, the reaction took place under an inert argon atmosphere; the reaction product was "titanium sponge" which was then ground down to small pellets for shipping to customers. There was a similar plant run by ICI near Runcorn. I was told that sodium was used because it produced a higher purity product, and that this was needed by NASA, one of the main customers.
Should the article talk about how "volatile" the metal halide is in air, or how "reactive" it is? If "volatile" is indeed meant, then the "in air" part should probably be omitted as the substance is going to be volatile anywhere.

NOT used as smoke screen any more?
There's an inaccurate statement that TiCl4 is no longer used as a smoke screen, because of the corrosive nature of the smoke. I dispute this statement for the following reasons:
1) TiCl4 replaces white phosphorous as a momentary (rapid) smoke generator in most armies because of the fire hazard and the risk of third party injury and death (collateral damage). So TiCl4 is the more humane option for momentary smoke screens.
2) It is in fact still used as a smoke generator, for example in the Swedish Rökgranat (rökgr) m/73 and m/81. — Preceding unsigned comment added by Student342 (talk • contribs) 17:30, 24 November 2016 (UTC)
- Whatever.... it is probably unimportant if this stuff is currently being used and by whom, so I converted the paragraph to something more generic. --Smokefoot (talk) 19:15, 24 November 2016 (UTC)
Literature report: 42658 references
As of today: 42658 references, of which 23426 have appeared since the year 2000, of which 127 are classified as reviews by Chemical Abstracts Service (mostly on materials and Ziegler-Natta it appears).--Smokefoot (talk) 22:09, 20 August 2017 (UTC)
