Cesium carbonate CAS 534-17-8
Cesium carbonate inorganic compound. Iro rakachena rakasimba pakupisa kwekamuri uye kumanikidzwa. Inonyungudika zvakanyanya mumvura uye inotora mwando nekukurumidza kana yaiswa mumhepo. Iyo aqueous solution ye cesium carbonate ine alkaline yakasimba uye inogona kuita neasidhi kugadzira inowirirana cesium munyu nemvura, uye kuburitsa carbon dioxide. Cesium carbonate iri nyore kushandura uye inogona kushandiswa seyakatangira mamwe cesium munyu. Inoshandiswa zvakanyanya mumhando dzemunyu cesium.
