Calcium polonide is an intermetallic compound with the chemical formula Шаблон:Chem2. It is made up of calcium and polonium. Rather than being found in nature, the compound is entirely synthetic, and difficult to study, due to polonium's high vapor pressure, radioactivity, and easy oxidation in air.

Structure

At atmospheric pressure, it crystalizes in the cubic rock salt crystal structure.[1] At a high pressure of around 16.7 GPa, the structure is predicted to transform to the caesium chloride-type crystal structure.[2]

Electronic properties

Based on theoretical calculations, calcium polonide is predicted to be a semiconductor.[3]
