Perovskite Crystal Lattice Structure

Perovskites are face centered cubic crystals with many potential electronic applications; buy this model kit for only $45.95 to study its novel lattice structure.

Perovskite the mineral has the chemical formula CaTiO₃. Other compounds such as BaTiO₃ & PbTiO₃ with this crystal lattice structures are also referred to as perovskites. The corners of the cube consist of positively charged cations while edges have smaller negatively charged anions.

This arrangement gives perovskites a distinctive three-dimensional framework that is highly symmetrical. The flexibility of this structure allows for a wide range of chemical compositions, which can be tuned to achieve specific electrical, optical, and mechanical properties. This tunability is a key reason why perovskites are so promising for applications like solar cells, light-emitting diodes, and other electronic devices.
