1. Yooj yim deliquescent. Sensitive rau lub teeb. Nws yog soluble hauv dej, soluble hauv ethanol, me ntsis soluble hauv methanol, thiab yuav luag insoluble hauv acetone. Tus txheeb ze ntom ntom yog 4.5. Lub melting point yog 621 ° C. Kub taw tes yog hais txog 1280 ° C. Lub refractive index yog 1.7876. Nws yog khaus. Toxic, LD50 (rat, intraperitoneal) 1400mg / kg, (rat, qhov ncauj) 2386mg / kg.
2. Cesium iodide muaj cov crystal daim ntawv ntawm cesium chloride.
3. Cesium iodide muaj zog thermal stability, tab sis nws yog yooj yim oxidized los ntawm oxygen nyob rau hauv cov huab cua ntub.
4. Cesium iodide kuj tuaj yeem oxidized los ntawm cov oxidants muaj zog xws li sodium hypochlorite, sodium bismuthate, nitric acid, permanganic acid, thiab chlorine.
5. Kev nce hauv solubility ntawm iodine nyob rau hauv aqueous tov ntawm cesium iodide yog vim: CsI + I2 → CsI3.
6. Cesium iodide tuaj yeem cuam tshuam nrog nyiaj nitrate: CsI + AgNO3 = = CsNO3 + AgI↓, qhov twg AgI (silver iodide) yog cov khoom daj uas tsis muaj dej.
