Titanates are compounds containing titanium, oxygen, and at least one additional metallic element. Some of the most common titanates are strontium titanate, barium titanate, calcium titanate, and dysprosium titanate. Strontium titanate, at room temperature, is a centrosymmetric paraelectric material with a perovskite structure. However, at low …

At room temperature, barium titanate is tetragonal and the deviation from cubic, (c − a) / 1 2 (c + a), is about 1%.All the atoms have the same x, y coordinates as in the cubic case but are shifted along the z-axis relative to each other by≈0.1 Å, producing the puckered arrangement shown in Fig. 16.3.The distortions from the ideal structure are exaggerated …
