Abstract:
Ferrite of different divalent transition metals were synthesized
at normal condition using established co-precipitation methods by
using simple salt precipitating from hot solution in temperature 9 0 C
as oxalate precipitate and followed by subsequent calcinations at
about 70 0 C to covert oxalate precipitate to oxide precipitate. The
synthesized ferrite include Nickel ferrite (Ni-Fer),Cobalt ferrite
(Co-Fer), Manganese ferrite (Mn-Fer),Copper ferrite (Cu-Fer),and Iron
ferrite (Fe-Fer).This ferrite material were characterized by various
spectroscopic
technique
such
as
Fourier
transfer
infrared
spectroscopy FT-IR, powder X-ray diffraction (XRD) and X-ray
florescence (XRF).
The FT-IR spectroscopic revealed the presence of Fe-O & M-O
band of respected divalent cations in cubic spinel structure and
absence or low level of impurities of residual precursors. The XRD
illustrated that the structure of ferrite material are of cubic single
spinel phase. The XRF analysis indicated the presence of the
incorporated metallic species but their percentages were found not
consistent with the empirical formula of normal spinel ferrite
M II Fe 2 O 4 .The deviation from normal spinels was assumed to be
related to the XRF spectrometer or the use of low purity grade
chemicals precursors.
