Several complex physico-chemical phenomena occur when
oxide surfaces are brought into contact with solutions of hydrolysable
salts. Both the hydrolysis and the surface chemistry of the
oxide are pH dependent, and by appropriate variation of pH the
adsorption of solution species at the surface may be controlled
to bring about such effects as charge reversal and coagulation of
the oxide particles, growth of a new phase at the surface, etc.,
many of which have technological significance.
