臭氧化鉀是一種無機化合物，化學式為KO₃。它是橙紅色的四方晶系晶體，空間群I4/mcm。^[7]

製備

臭氧化鉀可由氫氧化鉀和臭氧反應得到，^[1]但產率很低，只有5-10%。^[8]

6 KOH + 4 O₃ → 4 KO₃ + 2 KOH·H₂O + O₂

超氧化鉀用臭氧-氧氣的混合物（體積比2:98）進行臭氧化，也能得到臭氧化鉀。^[9]

KO₂ + O₃ → KO₃ + O₂

性質

臭氧化鉀可以和水劇烈反應，放出氧氣：^[1]

4 KO₃ + 2 H₂O → 4 KOH + 5 O₂↑

臭氧化鉀不穩定，在室溫時即可緩慢分解：^[1]

2 KO₃ → 2 KO₂ + O₂↑

它易溶於液氨，並有部分緩慢反應：

2 KO₃ + 2 NH₃ → NH₄O₃ + KNH₂
