Comments

Caesium Bromide is grown by sealed ampoule Stockbarger technique. CsBr is a soft pliable material. IUPAC International Union of Pure and applied Chemistry recommends the spelling as Cesium. UK Useage is Caesium. Solubility has historically been quoted as 124g/100mL at 25°C but Crystran Ltd tests 2021 have found this to be inaccurate.
