ABO3kiteet

ABO3kiteet refers to a specific crystalline structure adopted by compounds with the general chemical formula ABO3. This structural motif is named after the perovskite mineral, calcium titanate (CaTiO3), which was the first mineral identified with this arrangement. The ABO3 structure is a ternary oxide and is characterized by a cubic or pseudo-cubic lattice. In this structure, the 'A' site cation is typically larger and coordinated by twelve oxygen atoms, while the 'B' site cation is smaller and octahedrally coordinated by six oxygen atoms. The oxygen atoms form a framework, linking the 'B' site cations into a three-dimensional network of corner-sharing octahedra.

The ABO3 structure is highly versatile and can accommodate a wide range of elements in both the 'A' and 'B' positions, leading to a vast family of perovskite-related materials. These materials exhibit diverse physical properties, including ferroelectricity, piezoelectricity, ferromagnetism, ionic conductivity, and catalytic activity. This tunability makes ABO3 compounds highly significant in various scientific and technological applications. For instance, they are crucial in the development of solid oxide fuel cells, solar cells, memory devices, sensors, and catalysts. The specific properties of an ABO3 compound are strongly dependent on the chemical identities of the 'A' and 'B' cations, as well as any potential distortions from the ideal cubic structure.
