化学と産業
応用分野
使用Hafnium(IV) fluoride is used as Vacuum deposition.
調製方法
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.
