ABSTRACT
Doped vanadate ceramics with general formula Ca3-xInxVO8 were synthesized by using two
different precursors ( oxalate & citrates) to get maximum homogeneity inside the bulk of the material
where x = 0.05 and 0.25 mole. Structural and microstructural properties were monitoring by using
both of XRD and SEM evaluating that indium doped – calcium vanadate ceramic has the
semiconducting classical doubly perovskite phase as proved in the X-ray diffractogram, grain size of
the material bulk was found to be in between 1.57- 2.23 μm which are lower than those reported in
literatures. Magnetic measurements indicated that the In- doped – calcium vanadate ceramic exhibits
an semiconducting behavior confirming that indium – hole dopings enhance the paramagnetic
character and semi-conduction mechanism of the hexagonal perovskite phase. Furthermore 3D-AFM
investigations were made to study effect of indium doping on the surface topology and grain size in
the material bulk.
