Hafnium Iodide powder is a high-purity, easily sublimable metal halide widely used in hafnium metal purification, chemical vapor deposition (CVD), and electronic material synthesis. It appears as a white or pale yellow crystalline solid with excellent volatility and reactivity.
We offer Hafnium iodide powder in various specifications, customizable to meet specific customer requirements. All products undergo rigorous testing and come with accompanying analytical reports to ensure high quality and consistency.
Purity: 99.5% to 99.9%
Easy to sublime, suitable for chemical vapor deposition processes
Customized packaging (sealed in inert atmosphere) available
Wide Applications: Research, materials synthesis, and hafnium metal purification
Hafnium Metal Purification:In metallurgy, the thermal decomposition of hafnium tetraiodide can be used to effectively purify high-purity hafnium metal (Zr/Hf separation process).
Vapor Phase Deposition (CVD):HfI₄ is used as a precursor for the formation of HfO₂ thin films in the electronics industry, particularly for high-k gate dielectric materials.
Research Synthesis:It is used as a precursor or iodine source in research on high-purity inorganic compounds and organometallic chemistry.
We provide a full set of analytical reports for each batch of HfI₄ powder, including a Certificate of Analysis (COA), Material Safety Data Sheet (MSDS), and purity test report. Upon request, third-party testing and certification are also available to ensure transparent and reliable material quality.
