摘要

In this study, sodium titanium phosphate, NaTi_2(PO_4)_3 was synthesized in a pure form by using microwave energy. The NaTi_2(PO_4)_3 was obtained by mixing the initial reactants of TiO_2, (NH_4)_2HPO_4 and NaH_2PO_4·2H_2O with the molar ratio of 2:2:1 in a domestic type of microwave oven by using 2.45 GHz frequencies and at power of 750 W. The reaction was completed in 15 min. The microwave heating process was achieved by the help of the NaH_2PO_4·2H_2O which is the only microwave absorber in the initial mixture. The product was analyzed by X-ray diffraction (XRD) and fourier transform infra red (FT-IR) techniques and the results confirms the rhombohedral crystal structure of the NaTi_2(PO_4)_3 with the unit cell parameters of a = 8.4913(3), c = 21.7858(12) A, space group R3c and Z:6. The titled compound is also known as a member of NASICON materials. In future, it is possible to synthesize different types of sodium including NASICON compounds by the help of microwave susceptor agent of the NaH_2PO_4·2H_2O.
