Abstract
Manganese zinc pyrophosphate (Mn(2-x)ZnxP2O7 when x = 0.0, 0.5, 1.0, 1.5 and 2.0) ceramics were fabricated by conventionally mixing oxide using the normal sintering method. The samples were characterized by X-ray diffraction (XRD), Fourier transform infrared (FT-IR), Raman spectroscopy and scanning electron microscopy (SEM). The XRD results indicated that synthesized Mn(2-x)ZnxP2O7 systems have a pure monoclinic phase without the presence of phase impurities. The lattice parameters and crystalline sizes analyzed from XRD data were changed depending on the amount of added Zn2+ ion concentration in the Mn2P2O7 structure. The FT-IR and Raman results showed the fundamental vibrations of P2O74-ion and Mn-O or Zn-O, which confirmed the Mn(2-x)ZnxP2O7 formation. In addition, dielectric stability of temperature and frequency was observed in the composition, x = 1.0, with a dielectric constant value of 11.5 at 1 MHz.
