What Is The Crystal Structure Of Lanthanum Aluminate?

Lanthanum aluminate has a perovskite crystal structure, which is a type of cubic lattice with the chemical formula LaAlO3. In this structure, each lanthanum ion (La3+) is surrounded by six oxygen ions (O2-) arranged in octahedral coordination. The aluminum ion (Al3+) also sits at the center of an octahedron formed by six oxygen ions. The La and Al ions alternate in a regular pattern to form a three-dimensional network of corner-sharing octahedra. This structure gives lanthanum aluminate its high thermal stability and unique electrical properties, making it useful in various applications such as solid oxide fuel cells and electronic devices.
