Hafnium Iodide powder is a powdered compound of hafnium and iodine, usually yellow to orange in colour, which can be used at high temperatures to prepare high purity hafnium metal, and also plays a role in a number of specialised areas of materials synthesis and chemical research.
Properties
Appearance: Orange-red powder. The colour is one of the more distinctive features of its appearance and can be used for initial substance identification.
Density: Density 5.6 g/cm³, relatively dense, the weight of which requires consideration of containers and transport during storage and transport.
Melting point: melting point of 400 ° C (some data show that 449 ° C), the temperature of hafnium iodide powder will be changed from solid to liquid, in the use and processing need to pay attention to control the temperature, to avoid reaching the melting point to affect its performance.
Boiling point: The boiling point is 394℃ (741℉; 667K), which is relatively low, and it is easy to volatilise during the heating process, so it needs to be operated in a well-ventilated environment.
Crystal structure: monoclinic. The crystal structure determines the anisotropy of its physical properties, and it may have different physical properties in different directions.
Solubility: insoluble in water, belongs to non-water-soluble substances
Chemical formula: HfI₄, composed of two elements, hafnium (Hf) and iodine (I), is an inorganic compound.
Sensitivity: moisture sensitive, easy to absorb moisture in the air and chemical reaction, so it needs to be stored and used in a dry environment.
Reactivity: it is an intermediate in the process of preparing crystal rods of hafnium metal, and can participate in chemical reactions to generate hafnium metal under certain conditions. It has a certain degree of chemical activity and can react chemically with some oxidising and reducing agents.
Applications
Intermediate in the preparation of hafnium metal: Hafnium iodide is an important intermediate in the preparation of hafnium metal during the production of crystal rods. Through further processing of hafnium iodide, such as reduction and other chemical reactions, high purity hafnium metal can be obtained. Hafnium metal has good high temperature resistance, corrosion resistance and other properties, and has important applications in aerospace, nuclear industry and other fields.
Materials science research: it can be used in the synthesis and research of some special materials. For example, in the research and development of some new ceramic materials and composite materials, hafnium iodide powder may be used as a raw material or additive to help improve the performance of the material. Although this aspect of the application is still in the research stage, but has a certain potential value.
Chemical analysis field: in the chemical analysis process, hafnium iodide can be used as a reagent for the detection and analysis of certain substances. However, applications in this area are relatively few and their suitability needs to be determined based on specific analytical needs and methods.
