Hafnium tetrachloride

Description:

Hafnium tetrachloride (HfCl4) is an inorganic compound characterized by its white crystalline solid form at room temperature. It is a covalent compound, exhibiting a tetrahedral molecular geometry. Hafnium tetrachloride is highly soluble in organic solvents such as benzene and toluene but has limited solubility in water. It is known for its hygroscopic nature, readily absorbing moisture from the air, which can lead to hydrolysis and the formation of hafnium oxychloride. HfCl4 is primarily used in the production of hafnium metal and as a precursor in chemical vapor deposition processes for hafnium oxide thin films, which are important in semiconductor applications. The compound has a relatively high melting point and can be sublimed under vacuum. Due to its reactivity, particularly with water and bases, handling HfCl4 requires caution, as it can release hydrochloric acid upon contact with moisture. Overall, hafnium tetrachloride plays a significant role in materials science and advanced manufacturing processes.
