Potassium polonide is a chemical compound with the formula K<sub>2</sub>Po. It is a polonide, a set of very chemically stable compounds of polonium.
Potassium polonide is thermally more unstable and has stronger electron affinity than potassium telluride (K<sub>2</sub>Te).
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 300âÂÂ400 ðC. At higher temperature, this reaction may reverse.
Like sodium polonide, potassium polonide has the antifluorite structure.
