臭氧化钾是一种无机化合物，化学式为KO₃。它是橙红色的四方晶系晶体，空间群I4/mcm。[7]

制备

臭氧化钾可由氢氧化钾和臭氧反应得到，[1]但产率很低，只有5-10%。[8]

6 KOH + 4 O₃ → 4 KO₃ + 2 KOH·H₂O + O₂

超氧化钾用臭氧-氧气的混合物（体积比2:98）进行臭氧化，也能得到臭氧化钾。[9]

KO₂ + O₃ → KO₃ + O₂

性质

臭氧化钾可以和水剧烈反应，放出氧气：[1]

4 KO₃ + 2 H₂O → 4 KOH + 5 O₂↑

臭氧化钾不稳定，在室温时即可缓慢分解：[1]

2 KO₃ → 2 KO₂ + O₂↑

它易溶于液氨，并有部分缓慢反应：

2 KO₃ + 2 NH₃ → NH₄O₃ + KNH₂
