Powder‐metallurgical components in process engineering. Applications of structural parts made by powder metallurgy can be found in nearly all kinds of industries, especially the automotive industry, and the electrical and electronics industry. This paper describes applications of porous P/M materials for chemical technologies. Quite well known are sintered metal filter elements of different sizes in the form of tubes, plates, and cartridges. Porous P/M materials can also be used as flame resistors and silencers, for the dispersion of gases in liquids, for drying processes, and for homogenisation of various products. Almost all technically interesting alloys are available for these elements. New applications for porous metal structures are under development for the use of catalytically active reactor beds in solid bed reactors. It was found that some reactor bed materials are themselves active as catalysts. In such a reactor, the temperature gradient is very small, so that chemical reactions can be controlled much more efficiently.
