Indexing the Diffraction Patterns and Investigating the Crystal Structure of Pb-doped Strontium Ferrites

Abstract

Strontium hexaferrites were prepared in powder form by sol-gel auto-ignition technique and Pb was doped in different concentrations to attain the various compositions Sr1-xPbxFe12O19 (x = 0.00, 0.05, 0.10, 0.15, 0.20). Sintering treatment of the samples was made at 800 oC for the development of stable hexagonal phase. X-ray diffraction analysis of the samples was carried out for the confirmation and determination of crystal structure of the material. Data obtained from X-ray diffraction analysis helped in determining various parameters of the samples like lattice parameters, volume of the unit cell, crystallite size, bulk density of the samples, X-ray density and porosity of the samples.Keywords:Ferrites; Sol-gel method; X-Ray diffraction; Crystal structure.© 2013 JSR Publications.
