Description
Hafnium is available as 99.9% pure metal pieces. These are used in HfO synthesis mainly used as a dielectric. Owing to their sublimation properties the Hafnium chloride and Hafnium iodide are used as ALD precursors for deposition of Hafnium oxide in semiconductor industry. Recently , HfCl4 and HfI4 have also found applications as a scintillator. The high purity powders are sublimed and can be used to produce the Cs2HfCl6 along with CsCl beads from APL.
