In this work, we describe the preparation and characterization of KTiOPO 4 (KTP) powders and membranes. Potassium titanyl phosphate crystallizes at 550°C. Electrophoresis measurements indicate that the material surface is negatively charged. Membranes were fired at 550, 500 and 400°C and pore diameters were equal to 10, 5 and 1.2 nm, respectively. Water fluxes were measured and some results...
