Cesium carbonate CAS 534-17-8
Cesium carbonate wani sinadari ne na inorganic. Fari ne mai ƙarfi a yanayin zafi da matsin lamba na ɗaki. Yana narkewa sosai a cikin ruwa kuma yana shan danshi da sauri lokacin da aka sanya shi a cikin iska. Maganin ruwa na cesium carbonate yana da alkaline sosai kuma yana iya amsawa da acid don samar da gishirin cesium da ruwa daidai, da kuma fitar da carbon dioxide. Cesium carbonate yana da sauƙin canzawa kuma ana iya amfani da shi azaman abin da zai maye gurbin sauran gishirin cesium. Ana amfani da shi sosai a cikin nau'ikan gishirin cesium.
