Beschreibung

Allgemeine Beschreibung

Hafnium(IV) chloride, also known as hafnium tetrachloride, is commonly used as a precursor in the production of hafnium metal and various hafnium compounds. Additionally, it serves as a catalyst in certain organic synthesis reactions. Due to its reactivity and sensitivity to moisture, hafnium(IV) chloride is typically handled under an inert atmosphere.

Anwendung

Hafnium(IV) chloride can be used as:     

• A precursor in the synthesis of lithium hafnium phosphate, which is a solid electrolyte material used in lithium batteries due to its high ionic conductivity and chemical stability.      
• A catalyst in the acetalization process of various carbonyl compounds, including aldehydes and ketones.      
• A catalyst in the direct ester condensation of carboxylic acids with alcohols.    
• A high-capacity cathode material for lithium and sodium-ion batteries.
