|Cesium formate powder.|
Cesium formate, dissolved or suspended in water, is used as a drilling fluid for drilling deep oil wells. These solutions are extremely dense, allowing them to "float" rock chips and dust to the surface from the bottom of a deep well as it is being drilled.
The "purity" figure below, 75%, refers to the weight percent of cesium in cesium formate. Because cesium is such a heavy atom, it makes up most of the weight of the compound even though the formate group contains four other atoms.
I am extremely grateful to the Cabot Corporation for very kindly sending me a bottle full of this rather expensive compound, as well as jugs of cesium formate brine and suspension.
