Beryllium Fluoride

Molecule Structure Image

Description

 

Beryllium Fluoride is the inorganic compound. Beryllium fluoride can be made by the thermolysis of ammonium beryllium fluoride, (NH4)2BeF4.Beryllium Fluoride in the form of fluoroberyllate glass it has the lowest refractive index for a solid at room temperature of 1.275. It dispersive power is the lowest for a solid at 0.0093. It is used in biochemistry, particularly protein crystallography as a mimic of phosphate. Beryllium Fluoride forms a basic constituent of the preferred fluoride salt mixture used in liquid-fluoride nuclear reactors.
