초록
Nano-size beta calcium pyrophosphate(β-Ca2P2O7) powders with average grain size of 80 nm were prepared by sol gel method with calcium nitrate 4-hydrateCa(NO3)2 • 4H2O and different amount of diammonium hydrogen phosphate (NH4)2HPO4(0.4 and 0.6 molar) as calcium and phosphorus precursors. The pH of the system was maintained up to (pH = 10) by the adding of sodium hydroxide. The white precipitate stirred for 2 hour and washed with distilled water and filtered. Filtered cake was dried at 80 o C and calcined at 600 o C. The dried and calcined powders were characterized for phase composition using X-ray diffractrometry (XRD) and Fourier transform-infrared spectroscopy (FTIR). The particle size and morphology was studied using scanning electron microscopy (SEM).
