X-ray diffraction - Opis:
- 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.
