'''탄산 칼륨'''({{문화어|탄산칼리움}}<ref>평양 1999년 3월 19일발 조선중앙통신: "그 방법은 소성로먼지 가운데서 탄산칼리움을 포집하여 물로 우려낸 다음... "</ref>, {{llang|en|Potassium carbonate}}, K<sub>2</sub>CO<sub>3</sub>)은 [[물]]에 녹는 하얀 빛깔의 칼륨 탄산염으로, 알칼리 용액을 만들어낸다. 취하며 쓴 맛이 난다. 수소이온지수는 11.6pH이고 녹는점은 891도이다. 탄산 칼륨은 다른 소화성 물질에 비해 염분이 높은  성질이 있다.

== 공업 생산 ==
탄산 칼륨은 다음의 과정을 통해 생성된다.
: 2KOH + CO<sub>2</sub> &rarr; K<sub>2</sub>CO<sub>3</sub> + H<sub>2</sub>O
