Abstract
Pure calcium pyrophosphate (Ca2P2O7) and Mn doped Ca2P2O7 based ceramics were synthesized by sol–gel method, and were characterized using X-ray diffraction (XRD), Fourier transform infrared (FTIR), vibrating sample magnetometer (VSM), scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) spectroscopy. The average crystallite size and crystallinity are affected by the addition of lower amount Mn, whereas, the content of Mn having higher amounts did not cause a remarkable effect on these parameters. The bands belonging to the pyrophosphates were detected. The ceramics exhibit the paramagnetic behavior at room temperature and the magnetic susceptibility increases from 7.28 × 10–7 to 2.48 × 10–5 emu g–1 Oe–1 with the addition of Mn. The microstructure of the ceramics is affected by the content of Mn. All the samples are composed of the fine-grained particles, and no impurity is observed.

Keywords: Magnetic property, Sol-gel method, Ca2P2O7 ceramic.
