SrSnO3

Strontium stannate, with the chemical formula SrSnO3, is an inorganic compound. It crystallizes in a perovskite structure, a common and important structural motif in many oxides. This structure is characterized by the general formula ABO3, where A and B are cations and O is oxygen. In SrSnO3, strontium (Sr) occupies the A-site, and tin (Sn) occupies the B-site, with oxygen forming the surrounding octahedra.

SrSnO3 is typically a white or off-white powder. It is a refractory material, meaning it has a high melting point and is resistant to heat and wear. Its electrical properties can vary depending on synthesis conditions and the presence of defects or dopants, but it is generally considered an insulator or a wide-bandgap semiconductor. Research has explored its potential applications in areas such as solid oxide fuel cells, photocatalysis, and as a dielectric material due to its thermal stability and perovskite structure. The synthesis of SrSnO3 often involves solid-state reactions at high temperatures, where strontium carbonate and tin dioxide are mixed and heated. Other methods like sol-gel or hydrothermal synthesis can also be employed to achieve finer particle sizes and better control over stoichiometry.
