Elements: Titanium materials

August 5th, 2015

Episode 320 of 646 episodes

Stronger and more durable than steel, this glamorous metal crops up in sportscars, hip replacements and jewellery - but a new chemical process hopes one day to make it as common as steel. Prof Andrea Sella explains why this relatively widespread chemical element is so difficult to extract from its ore. Presenter Laurence Knight then heads to Yorkshire, where metallurgy pioneers Metalysis are trying to commercialise a novel way of doing just that - the so-called FFC Process. We also visit Epsom hospital, south of London, where orthopaedic surgery head Philip Mitchell explains why titanium makes such great bone implants, and Philip Dewhurst of mineral consultancy Roskill casts doubts on whether titanium will ever become cheap and ubiquitous, at least in his lifetime.
