HAFNIUM FLUORIDE Chemical Properties,Uses,Production
Chemical Properties
Off-white powder
Physical properties
White monoclinic crystals; refractive index 1.56; density 7.1 g/cm3; sublimes at 970°C.
Uses
Hafnium(IV) fluoride is used as Vacuum deposition.
Production Methods
Hafnium tetrafluoride is prepared by careful thermal decomposition of ammonium fluorohafniate in an oxygen- free atmosphere or by passing anhydrous hydrogen fluoride over hafnium tetrachloride at 300℃. Direct synthesis from the elements is incomplete because the product merely forms a film on the metal. Ammonium fluorohafniate can be prepared by crystallization from an aqueous hydrofluoric acid solution by adding ammonium fluoride.
