Hafnium Chloride Electrical grade

Hafnium Chloride is an excellent water soluble crystalline Hafnium source for uses compatible with chlorides. Chloride compounds can conduct electricity when fused or dissolved in water. Chloride materials can be decomposed by electrolysis to chlorine gas and the metal. They are formed through various chlorination processes whereby at least one chlorine anion (Cl-) is covalently bonded to the relevant metal or cation. Ultra high purity and proprietary formulations can be prepared.

Hafnium (IV) chloride is the inorganic compound with the formula HfCl4. This colorless solid is the precursor to most hafnium organometallic compounds. It functions as a Lewis acid and catalyst for certain alkylation and isomerism reactions. Hafnium and zirconium compounds are extracted from ores together and have very similar properties. The most common contaminant in HfCl4 is therefore ZrCl4, and commercial samples can contain several percent zirconium.

HfCl4 is the most common precursor for chemical vapor deposition of hafnium dioxide and hafnium silicate, used as high-k dielectrics in manufacture of modern high-density integrated circuits.
