What Are Perovskite Materials

A perovskite is any material with a crystal structure following the formula ABX3, which was first discovered as the mineral called perovskite, which consists of calcium titanium oxide (CaTiO3). Perovskites are generally cubic or octahedral in shape and are shiny and light to brown in color. They can be used to refine titanium, niobium, and rare earth elements, but only in large aggregates to be valuable.

 
Applications of perovskites

Perovskite material is a new type of inorganic non-metallic material with unique physical and chemical properties. The A site is a generally rare earth or alkaline earth element ion, and the B site is a transition element ion. Partial substitution of metal ions keeps its crystal structure basically unchanged, so theoretically it is an ideal sample for studying catalyst surface and catalytic performance.

Due to the stable crystal structure, it has unique electromagnetic properties, and high activity of redox, hydrogenolysis, isomerization, electrocatalysis, etc., these compounds, as a new type of functional materials, have great potential in the fields of environmental protection and industrial catalysis.

Perovskite composite oxides have a unique crystal structure, especially the crystal defect structure and properties formed after doping or can be used in solid fuel cells, solid electrolytes, sensors, high-temperature heating materials, solid resistors, and substitutes for precious metals. Redox catalysts and many other fields have become a research hotspot in the fields of chemistry, physics, and materials.
