Figure 2From: Crystal structure and electrical properties of bismuth sodium titanate zirconate ceramicsRefinement of Bi 0.5 Na 0.5 Ti 1-x Zr x O 3 ceramics. The refinement at (a) 0.20 mole fraction and (b) 0.80 mole fraction showed a rhombohedral phase and an orthorhombic phase, respectively.Back to article page
