On the formation of a refractory skeleton in composite materials. A review

Abstract

Papers on theoretical and experimental investigations into the formation of a refractory skeleton in composite materials have been analyzed. It has been shown that the critical parameters that describe the refractory skeleton are the contiguity of particles and dihedral angle. In the theory of the formation of a refractory skeleton certain results have been achieved in the establishing of interrelationship between the values of dihedral angle, contiguity, concentration of phases, and the conditions for the skeleton formation. The composition and structure of interphase boundaries of the refractory skeleton have been described and the thickness of the particles contact zone has been substantiated. Various technologies that allow one to actively influence the formation of the refractory skeleton have been considered and ways of the further investigations in the field have been suggested.
