Description :
The series of samples of composite of Cobalt substituted zinc ferrite and lead titanate with
composition (y) PbTiO
3
–
(1
-
x) ZnFeCoO
4
(x=0 to 0.50 and y=1) were synthesized by standard ceramic
method.
X
-
ray powder diffraction (XRD) patterns of all prepared samples confirms the
cubic spinel
structure in ferrite phase and tetragonal perovskite structure in ferroelectric phase of the composites. The
lattice parameters a and c for both the phases in these c
omposites vary slightly with the composition. The
X
-
ray density and porosity of the composite materials are in the moderate range as compared to that of
ferrite and ferroelectric phase. Hence the ferrites
-
ferroelectric composites find the applications in
microwave devices.
