Potassium polonide
Potassium polonide is a chemical compound with the formula K2Po. It is a polonide, a set of very chemically stable compounds of polonium.
Characteristics
Potassium polonide is thermally more unstable and has stronger electron affinity than potassium telluride.Production
Potassium polonide may be produced from a redox reaction between polonium hydride and potassium metal:It may also be produced by heating potassium and polonium together at 300–400 °C. At higher temperature, this reaction may reverse.
