Potassium carbonate siv kuj hu ua potassium puag (potash), molecular mis: K2CO3. Cov impure feem ntau hu ua oxaline, aleurine lossis pearl tshauv. Dawb crystalline hmoov. Qhov ceev 2.428g / cm3 (19 degree). Melting point 891 degree. High thermal stability, cua sov rau 1000 degree tsis decompose. Yooj yim deliquescence. Soluble hauv dej. Insoluble hauv ethyl ether thiab ethanol. Potassium carbonate siv muaj zog hygroscopic, yooj yim rau caking, ntev kev sib cuag nrog huab cua, yooj yim nqus carbon dioxide rau hauv potassium bicarbonate. Muaj peb hom hydrate ntsev: monohydrate ntsev, dihydrate ntsev thiab trihydrate ntsev. Lub saturated aqueous tov yog txias rau precipitate glassy monoclinic crystal hydrate 2K2CO3 · 3H2O. Thaum 100 degree, cov dej siv lead ua poob.
