Most titanium metal today is made by the Kroll process (see box on p. 00), in which titanium tetra-chloride is reduced to titanium metal by reaction with molten magnesium. A small amount is also produced with the Hunter process, in which sodium replaces the magnesium. ITP's Armstrong process is based on the same chemistry as Hunter, but there the similarity ends. Building on their experience ...

TITANIUM - ASM International

However, the current titanium production system is extremely labor and capital intensive. Titanium is expensive only because the current process for re-fining the ore to metal is a multi-step, high tem-perature batch process. This article will first de- scribe current titanium technology, and will then discuss four of the most promising approaches to reduce the cost of titanium. These include ...

GCSE CHEMISTRY - Titanium - Extraction - Rutile - …

The extraction of titanium uses the Kroll process. Titanium ore is called rutile. Rutile contains titanium dioxide - TiO 2. Titanium dioxide is converted into titanium chloride - TiCl 4. Titanium is more reactive than carbon but it is not extracted by electrolysis because titanium chloride is covalent and therefore does not conduct electricity. Titanium chloride is a yellow liquid (melting ...
