Crystalline Phase Formation in a Foam Glass Matrix and its Effect on Material Performance

Аннотация

The results of studies on the formation of a crystalline phase in the matrix of foam glass as well as the influence of this phase on the performance of a material (strength in compression, density, and others) are presented. The particularities of the technological process of foam-glass synthesis taking account of crystallization are shown. It is found that an amorphous-crystalline frame (crystalline-phase content to 20%) where crystalline inclusions of definite size (35 – 50 nm) play a reinforcing role is necessary in order to increase the strength of the foam glass.
