Hafnium(IV) oxychloride hydrate
Hafnium(IV) oxychloride hydrate (CAS: 15461-28-6) is a crystalline hafnium salt with the linear formula HfOCl₂ · xH₂O. Its anhydrous molar mass is 265.40. This high-purity material, assayed at 99.99% on a trace metals basis (excluding zirconium), serves as a crucial starting material in the synthesis of advanced phosphors for X-ray applications, specifically HfGeO₄ and HfGeO₄:Ti.
Phosphor Synthesis
Utilised as a precursor in the production of hafnium germanate phosphors, such as HfGeO₄ and HfGeO₄:Ti. These materials are essential for X-ray imaging applications due to their luminescent properties.
Materials Science Research
Serves as a valuable research chemical for exploring novel hafnium-based materials. Its defined purity makes it suitable for precise material characterisation and development.
Ceramic Precursor
Can be employed in the development of specialised ceramics. Hafnium compounds are known for their high melting points and chemical stability, making them useful in advanced ceramic formulations.
