In this type of colloidal system, the dispersed phase does not have an affinity for the dispersion medium so the colloid is not readily formed. They are also known as irreversible sols as they cannot be reconstituted by simply adding dispersion medium after precipitation. They are unstable and can coagulate easily on adding electrolyte, shaking or heating. Lyophobic colloids can be prepared by special methods and require a stabilising agent. Examples of lyophobic colloids are metals and their insoluble compounds such as sulphides.

A Lyophobic Colloid is a substance that contains large molecules that do not properly dissolve in liquids. The term Lyophobic comes from “Lyo” which means solvent and “Phobic” which means hating. When such colloids dissolve in a liquid, a very weak attraction force exists between the liquid molecules and colloidal particles and system does not readily become a colloidal solution.
