PROCESS FOR THE FLUX SYNTHESIS OF CRYSTALS OF THE KTIOP04 TYPE OR MONOPHOSPHATE OF POTASSIUM AND TITANYL

摘要

The process of synthesis of crystals of the KTP type comprises dissolving a mixture of titanium oxide and of oxides, oxide precursors or salts of the constituents of the desired compounds or of compounds of the KTP type prepared beforehand in at least one alkali metal halide by heating at a plateau temperature of 1100 DEG -650 DEG C., cooling to a temperature close to ambient at a rate lower than about 50 DEG C./h.
