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.

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 molecules and clusters differ in structure and interaction force.

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