Mechanical performance of foam glass with nanoscale structure elements

Abstract

The paper presents experimental data on studying the strengthening of glass foam material. Glass foam material is foamed glass of increased strength achieved due to nanoscale structural elements. Glass foam is obtained through thermal treatment of noncrystalline matrix containing crystalline material in the silica state. It is shown that strengthening of glass foam material is achieved by structuring the noncrystalline partition. New technique of strengthening is proposed due to the formation of nanoscale globules of noncrystalline matrix. Self-organization of spherical nanoscale globules. New technique for glass foam strengthening. For the first time the phenomenon of strengthening interpore partition of glass foam was established. The principle of the process consists in the formation of noncrystalline matrix with a specific globular structure. © Published under licence by IOP Publishing Ltd.
