Paper Title:
Synthesis of Single-Phase Nanocrystalline YIG by Co-Precipitation: The Influence of pH Value of Precursor Solution and Calcinating
  Abstract

Single-phase nanocrystalline YIG powders have been successfully synthesized through chemical co-precipitation methods. The influence of pH value of the precursor solution and calcinating conditions (temperatures ranging from 700 to 900°C and times ranging from 0.5 to 12 hours) on the purity and grain size of the single-phase nanocrystalline YIG powders were investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM) technique. The results show that a pure single-phase YIG powder was obtained as the pH value of precursor solution above 10 and the YIG grain grows bigger as calcinating temperature and time increased. Finally, the optimal condition to form single-phase nanocrystalline YIG with the smallest grain size is calcinating at 750°C for 7 hours.
