Applications
1. Chemical Vapor Deposition (CVD):
Hafnium Chloride is used as a precursor in CVD to produce thin films of hafnium dioxide (HfO₂) and other hafnium-based materials. HfO₂ is widely used in semiconductor manufacturing, particularly in high-k dielectric materials for gate insulators in transistors.
2. Material Synthesis:
It is employed in the preparation of other hafnium compounds, such as hafnium carbide (HfC), hafnium oxide (HfO₂), and various alloys.
3. Catalysts:
Hafnium Chloride can act as a catalyst or catalyst precursor in organic synthesis and polymerization reactions.
4. Nuclear Applications:
Hafnium’s excellent neutron absorption properties make HfCl₄ useful in the nuclear industry, where hafnium-based materials are employed in control rods and other nuclear reactor components.
5. Metallurgical Uses:
Hafnium is often alloyed with other metals to improve corrosion resistance and high-temperature stability, particularly in aerospace applications.
