Yintoni i-Cesium carbonate CAS 534-17-8?

I-Cesium carbonate yi-inorganic compound. Iqinile emhlophe kwiqondo lokushisa kunye noxinzelelo. Inyibilika kakhulu emanzini kwaye ifunxa ukufuma ngokukhawuleza xa ibekwe emoyeni. Isisombululo esinamanzi se-cesium carbonate sinamandla e-alkaline kwaye sinokusabela nge-asidi ukuvelisa ityuwa ye-cesium ehambelanayo kunye namanzi, kunye nokukhulula i-carbon dioxide. I-Cesium carbonate kulula ukuyiguqula kwaye ingasetyenziswa njenge-precursor yezinye iityuwa ze-cesium. Isetyenziswa kakhulu kwiintlobo zetyuwa ye-cesium.
