'''Kaliumoxid''' (K<sub>2</sub>O) är en [[kemisk förening]] av [[kalium]] och [[syre]].<br />
<br />
==Egenskaper==<br />
Det är en starkt [[bas]]isk [[oxid]] som i kontakt med vatten bildar [[kaliumhydroxid]], och är därför svår att isolera i ren form. Vid ca&nbsp;350&nbsp;°C sönderfaller den till [[kaliumperoxid]] (K<sub>2</sub>O<sub>2</sub>) och rent kalium.<br />
<br />
==Framställning==<br />
Kaliumoxid kan framställas genom att blanda kaliumperoxid och kalium.<br />
:<math>\rm K_2O_2 + 2\ K \rightarrow 2\ K_2O</math><br />
<br />
Alternativt kan [[kaliumnitrat]] användas i stället för kaliumperoxid.<br />
:<math>\rm 2\ KNO_3 + 10\ K \rightarrow 6\ K_2O + N_2</math><br />
<br />
