Calcium polonide (CaPo) is an
intermetallic compound made up of
calcium and
polonium. Rather than being found in nature, the compound is entirely
synthetic Synthetic things are composed of multiple parts, often with the implication that they are artificial. In particular, 'synthetic' may refer to:
Science
* Synthetic chemical or compound, produced by the process of chemical synthesis
* Synthetic o ...
, 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 crystal salt structure.
At a high pressure of around 16.7 GPa, the structure is predicted to transform to the
caesium chloride
Caesium chloride or cesium chloride is the inorganic compound with the formula Cs Cl. This colorless salt is an important source of caesium ions in a variety of niche applications. Its crystal structure forms a major structural type where each ...

Electronic properties
Based on theoretical calculations, calcium polonide is predicted to be a
semiconductor.
