Synthesis crystallographic characterization and electrical properties of titania and zirconia based ceramic materials Ashish Bohre

Doctoral Thesis / Dissertation from the year 2012 in the subject Chemistry - Materials Chemistry, grade: None, , language: English, abstract: Syntheses of all the three groups of materials (NZP, CZP and Perovskite) have been successfully carried out by solid state ceramic route resulting in the formation of single phase high density material in all the cases. Preliminary characterization was carried out by X-ray diffraction followed by complete crystal characterization by Rietveld method. Their crystal chemistry has been investigated using software's like CRYSFIRE, Check cell, Winploter etc. Finally, structures have been refined to a satisfactory convergence using GSAS software. The structure model in each case has been given with the help of graphics software's like PLATON, Crystal maker, Diamond and ORTEP etc. Particle size calculation using Scherrer's formula suggest that crystallite size along prominent reflections belongs to nano range in most of the synthetic phases. On the basis of results emerged after Rietveld refinement of each group of materials.
