Abstract

We describe three sets of experiments on suspensions of 'hard-sphere' colloids. Suspensions of equal-sized particles exhibit the hard-sphere freezing and glass transitions. Mixtures of spheres of two different sizes can form the ordered binary crystals AB2 and AB13. The addition of non-adsorbing polymer to a one-component suspension leads, through the depletion mechanism, to a range of phase behaviour, which includes colloidal gas, liquid, crystal and gel.
