Isetyenziselwa ntoni iCesium carbonate?

I-Cesium carbonate sisiseko esikhangayo esifumana izicelo ezininzi nangakumbi ekudibaniseni i-chemistry. I-Cesium carbonate ikwasetyenziswa njenge-catalyst ye-Aerobic oxidation yee-alcohols eziphambili. Njengemathiriyeli ekrwada yokuvelisa iikhompawundi ezahlukeneyo ze-cesium, i-nitrate ye-cesium isetyenziswa kakhulu kwi-catalyst, iglasi ekhethekileyo kunye neeseramics njl.
