Potassium, interacting with oxygen, forms potassium oxide:
4K + O2 = 2K2O.
But, most often, during combustion, potassium turns into potassium superoxide (superoxide), the reaction of which looks like this:
K + O2 = KO2.
You can also observe the decomposition of potassium superoxide (superoxide) in a vacuum at a temperature of 290 degrees Celsius:
2KO2 = K2O2 + O2.
KO2 is a strong oxidizing agent.
