Abstract

Powders of the Nasicon material NaTi2(PO4)3 were directly synthesized at ultra-low temperature. NaTi2(PO4)3 was obtained by mixing the initial reagents titanium hydroxide, 85 % H3PO4, and NaH2PO4·2H2O at 85 °C for 3.5 h or at 125 °C for 1.5 h. The raw materials and synthesized products were characterized for purity, crystal structure, particle size, and powder morphology by thermogravimetric analysis, differential scanning calorimetry, X-ray diffraction (XRD), Fourier-transform infrared spectroscopy, scanning electron microscopy (SEM), and UV–visible diffuse reflectance spectroscopy. XRD results revealed that NaTi2(PO4)3 powders with rhombohedral crystal structure were synthesized at 85 and 125 °C. SEM patterns showed that the as-prepared products were agglomerated and that each of the agglomerations consisted of many small grains 50–80 nm in diameter.
