Abstract
A technique was tested for structuring a finely dispersed bulk ferrosilicoaluminum powder by cryogels based on an aqueous poly(vinyl alcohol) solution to prepare products of a desired shape using porous nitride-containing ceramics as a structural material. The physical and mechanical properties of the produced samples were investigated. It was found that the materials obtained after preliminary cryostructuring of the initial powder and subsequent self-propagating high-temperature synthesis in a nitrogen atmosphere are characterized by high strength and porosity.
