====Armstrong process====
[[Titanium powder]] is manufactured using a [[flow production]] process known as the [[Armstrong process]]<ref name=Roza2008p25>{{harvnb|Roza|2008|p=25}}</ref> that is similar to the batch production [[Hunter process]]. A stream of titanium tetrachloride gas is added to a stream of molten sodium; the products (sodium chloride salt and titanium particles) is filtered from the extra sodium. Titanium is then separated from the salt by water washing. Both sodium and chlorine are recycled to produce and process more titanium tetrachloride.<ref name="ECI online">{{cite web |title=Titanium |date=15 January 2015 |website=The Essential Chemical Industry online |series=CIEC Promoting Science |publisher=[[University of York]] |location=York, UK |url=http://www.essentialchemicalindustry.org/metals/titanium.html}}</ref>
