Porous tungsten is a material with a wide range of applications, and its use is closely related to its internal porous structure. The following are the main applications of porous tungsten:
Aerospace field
Porous tungsten is widely used in the aerospace field due to its high melting point, low density, and good thermal stability. It can be used as a material for high-temperature components, such as nozzles and combustion chambers of rocket engines, to withstand extreme high temperature environments.
Electronic field
Porous tungsten has high conductivity and thermal emissivity, making it suitable for the production of electronic devices. For example, it can be used as a cathode material for microwave electronic tubes, vacuum electronic devices, etc., to improve the performance and stability of equipment.
Metallurgy and chemical industry
Porous tungsten can be used as a filtering material in metallurgical processes to filter impurities in molten metals. At the same time, it can also serve as a catalyst carrier for chemical reactions, providing a large specific surface area and promoting the progress of the reaction.
High temperature fluid filtration
The porous structure of porous tungsten endows it with excellent filtration performance and can be used for the filtration and separation of high-temperature fluids, such as gas separation and liquid filtration.
In addition, porous tungsten can also be used to make sheets, rods, and shaped parts, as cathode materials for modern microwave vacuum devices, frameworks for sweating materials, high-temperature gas distribution materials, and filtering materials.
Overall, porous tungsten has a wide range of applications, with its high melting point, low density, low coefficient of thermal expansion, and high strength, making it of great value in various fields. With the advancement of technology and continuous improvement of processes, the application fields of porous tungsten will further expand.
