Solid clathrate solutions

The classification of solid clathrate solutions may be subdivided into three types: interstitial solutions, those with the substitution of one guest by another and those with the substitution of the particles in a host framework is given. All these types of solutions are illustrated by experimental (or computed) state diagrams of binary and ternary systems of guest-host and host-guest1-guest2 kinds, where host components are water, urea, thiourea and hydroquinone.
