Effect of Calcination Process on Characterization of the 〖Co〗_(1-x ) 〖Zn〗_x 〖Fe〗_2 O_4 Nanoparticles by Co-Precipitation Method

Abstract

The Nanoparticles ( . with x = 0.0, 0.1, 0.3, 0.5, 0.7, 0.9 and 1, With exposure to a calcination temperature of 100, 300, 600 and 900 °C ) synthesized  by  the Co-precipitation method .The  structural and  magnetic  properties  of the  products  were  determined  and  characterized  in  detail  by  X-ray  diffraction  (XRD),  High Resolution -Transmission Electron Microscope (HR-TEM), Energy Dispersive X-ray Spectroscopy (EDX) , Fourier Transform Infrared (FTIR) and  vibrating  sample  magnetometer (VSM). These results provided that all the samples prepared at the nano-scale. X-ray analysis showed that the samples were  cubic  spinel structural ( kind  of  inverse  spinel  oxide).The crystallinity is improved with the  increases calcination temperature  for all samples and that proved by the FT-IR , XRD  and EDX results and compound  purity fabricated. HR-TEM analysis showed that nanoparticles size and the shape based on the Zn concentration & the calcination temperatures and also indicates that degree of agglomeration for all samples. VSM analysis showed that The C4 (  at 600°C) is best sample in Magnetic &structure properties where it’s super-paramagnetic behavior.
