Used as a precursor in the synthesis of hafnium-based materials for catalytic applications, particularly in oxidation reactions. Employed in the preparation of hafnium oxide coatings via sol-gel processes, which are applied in optical and electronic devices due to their high refractive index and thermal stability. Serves as a dopant in the production of specialty ceramics and refractory materials, enhancing mechanical strength and resistance to heat. Also utilized in research settings for developing new hafnium-containing complexes with potential use in nuclear reactor components, owing to hafnium's high neutron absorption capacity.
