extraction of titanium chemguide

Titanium extraction. The overall process. Titanium is extracted from its ore, rutile TiO 2. It is first converted into titanium(IV) chloride, which is then reduced to titanium using either magnesium or sodium. Conversion of TiO 2 into TiCl 4. The ore rutile (impure titanium(IV) oxide) is heated with chlorine and coke at a temperature of about

Titanium Alloys Corrosion and Erosion Resistance

Mar 27, 2002· Hence, titanium is resistant to attack in mixtures of strong sulphuric and nitric acids, hydrochloric and nitric acids and even in strong hydrochloric acid containing free chlorine. The presence in solution of cupric or ferric ions also reduces the corrosion rate, as does alloying with noble metals or the use of an anodic protection technique.

GCSE CHEMISTRY Titanium Extraction Rutile Titanium

Extraction of Metals. Extraction of Titanium.. 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.
