GENERAL INTRODUCTION:
Hafnium Tetrachloride is an inorganic compound in the form of colorless crystals or powder. It reacts violently with water, has strong hygroscopicity, and is highly susceptible to hydrolysis.
-
It is used in chemical vapor deposition (CVD) for semiconductor manufacturing,suitable for high-dielectric materials and insulating layers.
-
It is widely applied in organic chemical reactions as a catalyst precursor.
-
It serves as a raw material for hafnium in the production of electronic components.
