$BaTiO_3$ crystallizes in the prevoskite structure. This structure may be described as a cubic lattice with barium ions occupying the corner of the unit cell, oxide ions occupying the face- centers and titanium ion occupying the center of the unit cell. If titanium is described as occupying holes in the BaO lattice, what types of hole does it occupy? What fraction of this type of hole does it occupy?Can you suggest a reason why it has certain holes of this type but not other holes of the same type?
