Cubic and orthorhombic KNbO<SUB>3</SUB> have been synthesized under hydrothermal conditions respectively by tuning impurities and alkali concentration in initial reaction compositions, and characterized by X-ray diffraction, Laser Raman, Infrared and X-ray photoelectronic spectroscopies. Phase transitions of resulting niobates induced by pressure at high temperatures were investigated in comparison with hydrothermal pressure effect. Mechanisms of stabilization of cubic KNbO<SUB>3</SUB> were discussed.
