Porous SHS-Materials Based on Iron Oxide and Aluminum with Additions of Alloying Elements

Abstract

An optimum charge composition is developed for preparing porous permeable cermet SHS-materials with prescribed operating properties for cleaning exhaust gases of industrial installations and internal combustion engines. Physicomechanical properties of the materials obtained are determined with a different content of charge components and the range of vibration frequency is established suitable for material operation as filters. It is shown that addition of 0.5 – 1.5 wt.% of alloying elements to a charge increases SHS-material mechanical strength and shock resistance.
