ABSTRACT:
Method for fabricating a filter or catalytic reactor for hot exhaust gases, which includes a filter bed made from a frangible material such as steel wool or the like. The latter is confined and formed into a quasi-rigid body by application of an initial outer hardenable surface of a rigidizing material. Thereafter the preformed bed in an unconfined state, is treated to provide it with a uniform coating to a desired thickness in anticipation of being fitted into an appropriately shaped casing.
