Effect of Sintering Temperature on The Crystal Structure and Characteristic of Conductivity and Permittivity of Ba(2-x)Nd(x)TiF2O5

Barium diiron tetraoxide Ba(2-x)Nd(x)TiF2O5 has been synthesized by mechanical milling method. Ba(2-x)Nd(x)TiF2O5 is made from raw material of BaCO3, Nd2O3, Fe2O3 and TiO2 according to the composition of stoichiometry through weight comparison. The four raw materials are inserted into the vial, then mixed with milling techniques for 2 hours. Then the mixture was sintered using a furnace with a temperature variation of 800 °C, 900 °C and 1000 °C for 5 hours. Phase analysis was tested using XRD (X-ray Diffractometer) which was used to determine the crystal structure and crystallite size. Conductivity and permittivity characteristics of materials are measured using LCR meters. XRD analysis results show that the barium iron tetraoxide phase has been formed with crystallite size rising with increasing sintering temperature. While the characteristics of conductivity and permittivity as a function of frequency decreases and increases with increasing sintering temperature. It was concluded that the effect of sintering temperature can improve the conductivity and permittivity characteristics of the material.
