The Role of SiC in the Formation of the Structure of Microfiltration Layers of Porous Aluminosilicate Ceramics

Abstract

The regularities of sintering of finely dispersed mechanically activated powders, which differ from the known sintering processes of aluminosilicates by the synthesis on the surface of particles of aggregates of chemically and wear-resistant SiC compounds with sizes of 200–500 nm and that establish a relationship between the conditions for the formation of silicon carbide in the aluminosilicate–C system, have been studied, which made it possible to develop the foundations of a controlled process formation of porous materials with a microfiltration layer of carbon-containing compounds on an aluminosilicate basis.
