As a ray shielding material, tungsten-based composite material does not have the disadvantages of secondary toughening radiation, low hardness, and toxicity that exist in lead alloys and lead-containing glasses. Therefore, tungsten-based composite material is regarded as a potential substitute for lead to be used in medical shielding.

Tungsten trioxide is an important electrochemical material for saving energy and protecting environment. You know, many people are becoming aware of the importance of renewable energy resources with the growth of world population and the subsequent growth of demands for energy. While the uncontrollable and periodic nature of these energy resources has intensified the need for an efficient energy savers system.

Tungsten alloy leaf can be applied to multileaf collimator - an important part of medical linear accelerator. And there are many tungsten alloy leaves arranged closely to replace a whole lead block on the head of accelerator. The distance between each tungsten alloy leaf is very small. If dust particles or other dirty things settle on tungsten alloy leaves, it will cause the multileaf collimator to malfunction, so these leaves should be cleaned. Well, how to clean tungsten alloy leaf of multileaf collimator?

Tungsten trioxide is a new type of electrochromic material that is able to reversibly and persistently change its optical properties at an external voltage. Tungsten trioxide is considered as one of the most promising candidates for fabricating energy-saving smart window.
