There are significant differences between porous tungsten and regular tungsten in multiple aspects.
Firstly, structurally speaking, porous tungsten is a material composed of a rigid framework and internal pores, with a large number of pores. These pores give porous tungsten unique properties in density, specific surface area, permeability, and other aspects. In contrast, regular tungsten does not have this porous structure, and its physical and chemical properties are therefore different from porous tungsten.
Secondly, from the perspective of application fields, porous tungsten is widely used in aerospace, electronics, metallurgy, chemical and other fields due to its unique pore structure and properties. For example, it can be used as a manufacturing material for high-temperature components, as a cathode material for electronic devices, and as a filtering and separation material. However, regular tungsten is mainly used for manufacturing filaments, high-speed cutting alloy steel, superhard molds, etc., and its application fields are relatively limited.
In addition, the preparation process of porous tungsten is relatively complex, requiring the use of powder metallurgy and other methods to prepare materials with specific pore structures and properties. The preparation of regular tungsten is relatively simple and can be obtained through smelting and other methods.
In summary, there are significant differences between porous tungsten and regular tungsten in terms of structure, performance, and application fields. Porous tungsten plays an increasingly important role in modern technology and industrial development due to its unique structure and properties.
