Abstract

The results of comparative studies of the structure and properties of two-layer filter materials based on finely dispersed nickel powder are presented, in which the substrates were formed using hollow spheres and carbamide as pore-forming agents. The properties of the layers forming the structures of these two-layer materials, as well as the composite biporous material properties consisting of a mixture of hollow spheres of finely dispersed nickel powder and finely dispersed nickel powder are studied. The prospects for using hollow spheres to create two-layer filter materials are shown.
