Tungsten diiodide clusters can be used as X-ray contrast agents in interventional radiology. Tungsten diiodide cluster is a general term for a certain number of tungsten diiodide atoms or molecules, with a high degree of photoluminescence, this property makes it an excellent material for X-ray contrast agents.

Tungsten diiodide molecules and clusters differ in structure and interaction force.

Deuterium in tungsten-based materials can be removed by isotope replacement and thermal desorption. Tungsten-based material is a kind of tungsten-based alloy material composed of other elements, which has the characteristics of high melting point, high hardness, and high sputtering threshold, and is widely used in the field of nuclear fusion energy.

Tungsten diiodide is a class of inorganic compounds with a black powdery appearance that has the following chemical properties.

The valence electron arrangement of tungsten does not follow hund's rules. Tungsten is one of the transition metal elements in the sixth period (second long period) of the periodic table of elements VIB group. Transition metal elements are obviously different from other elements because of their unfilled valence layer d orbitals based on the eighteen-electron rule.

Tungsten diiodide (chemical formula: WI₂) is a kind of inorganic compound formed by the reaction of tungsten and iodine, which has the following chemical properties.

Tungsten diiodide (WI₂) is an inorganic compound composed of the transition metal element tungsten and the halogen element iodine. It has many chemical properties, which will be described one by one below.

A small amount of tungsten diiodide has low theoretical toxicity and will not harm health.

A tungsten iodide lamp is a kind of tungsten lamp filled with the halogen element iodine and belongs to a new generation of incandescent lamps In an iodine-tungsten lamp, the evaporation of iodine-tungsten circulating tungsten is effectively suppressed, and the problem of blackening glass shell is solved.Iodine tungsten lamp as a thermal radiation source has some potential safety hazards, so there are corresponding requirements and precautions for its installation and use.

There are tungsten vapor, iodine vapor, tungsten iodide gas and inert gas in the iodine tungsten lamp.
