Porous tungsten is a powder metallurgy tungsten product with a large number of pores inside, and its porosity is generally above 15%, and its use is closely related to porosity. It has good properties such as high temperature resistance, corrosion resistance, high specific surface area, and high permeability. According to the different raw materials used for preparation, porous tungsten can be divided into non spherical porous tungsten, spherical porous tungsten, and tungsten fiber porous tungsten. Among them, non spherical porous tungsten is the most widely used, while the latter two are used in special circumstances. When very uniform pores are required, use spherical porous tungsten made of spherical powder; When increasing strength is required, tungsten fibers are usually used to make tungsten wire reinforced porous composite materials.
Porous tungsten has a wide range of applications in various fields, including but not limited to aviation, electronics, high-temperature, and more. In these fields, the main application of porous tungsten is based on its intrinsic characteristics and utilizes functions such as pore connectivity, filling, storage, and filtration. For example, it can be used as a substrate material for reserve diffusion tungsten thermocathodes, as a framework for W-Cu composite materials prepared by infiltration method, and also as a high-temperature fluid filtration material.
