ABSTRACT

Spectral and Electrical Investigations of Zirconium Doped 212– Bi- Sr-Vanadate Ceramics

Khaled M. Elsabawy

ABSTRACT

Thepresent investigation study the synthesis of formula Bi2SrV2-x ZrxO9, where (x= 0.05, 0.1, 0.2, 0.3, 0.6) which was carefully synthesized and processed by using solid state reaction route and sintering temperature at 850oC for 10 hrs. XRD – analysis of the prepared samples proved that zirconium-dopant can substitute successfully until x = 0.6 mole on the Bi-layered perovskite crystal structure. Zr - dopings have slight effects on both ESR-signals and conduction mechanism of Zr-doped Bi-Sr-VO regime. Electrical measurements indicated that the energy gap Eg and number of electrons in conduction band Ncb increase as the ratio of Zr doping increases from x = 0.05 till x = 0.6 mole respectively . Keywords: 212-Bi-Vanadates; Zr – Doping ; Perovskite; Ceramic; X- ray; ESR; IR.
