Abstract
A filtering cartridge made of compacted and sintered particles is manufactured from a powder consisting of chromium or a chromium alloy with at least 70% Cr by weight and a particle size of the chromium particles between 160 .mu.m and 500 .mu.m. Filtering cartridges of this type can be used advantageously, particularly in gas clarification for energy production by biomass gasification or coal gasification, in cracking processes in the petroleum industry, as well as for the production of melamine resin.
