      Abstract:

        In order to modify the optical properties of potassium titanyl   phosphate (KTiOPO4),   an important component in nonlinear optical systems, it is   desirable to substitute the potassium ions which occupy sites in   channels with windows defined by six oxygen atoms. In the course   of ion-exchange reactions using molten salts containing sodium,   lithium and hydrogen ions, a number of reactions were observed   which led to compounds other than those expected from mere   ion-exchange. The nature of these reactions is discussed in terms   of the heats of formation of the compounds involved.
