Stabilization Studies of Crystal Structure of Optimally Th-Doped Lead Zirconate Perovskite

The optimally thorium-doped Pb0.9Th0.1ZrO3 was selected for studying thorium doping effect on the structural parameters of lead zirconate crystal. The investigations were made on the low concentrations range of thorium doping 0.0 ≤ x ≤ 0.25 mole. The present investigations are concerned by confirming that thorium dopings play an important role as stabilizing agent inside internal structure of crystal lattice of Pb1-xThxZrO3 where x = 0.1 mole. XRD-measurements indicated that Thorium dopant substitutes successfully on the A-sites of lead zirconate without damaging the main crystal structure at x = 0.1 mole. Visualization and theoretical investigations were concerned by matching and comparison of bond distances ,torsions on angles of investigated compound to clarify success of thorium doping on the perovskite structure.
