  • Chemistry of Titanium - Chemistry LibreTexts

    Titanium is very expensive because it is awkward to extract from its ores - for example, from rutile, \(TiO_2\). Whilst a biological function in man is not known, it has excellent biocompatibility--that is the ability to be ignored by the human body's immune system--and an extreme resistance to corrosion. Titanium is now the metal of choice for hip and knee replacements.
