Structure of refractory materials based on local mineral raw

Abstract

The paper is devoted to the results of microscopic analysis of the structure of fire-resistant materials developed on the basis of local mineral raw materials. The authors point out that in this regard, a special place is occupied by the microscopic analysis of refractory materials, because the use of various radiation and various designs of microscopes from optical to electronic requires various special preparation of objects and special methods for deciphering the observed images. Moreover, the use of these methods in relation to the fire-resistant compositions obtained during the experiments, consisting of kaolin, wollastonite, soda water glass, silica, finely dispersed thermovermiculite, silicon dioxide, dolomite, etc., demonstrates their microrelief morphology, which gives rise to other experiments related to increasing the quality of fire resistance of the objects under study.
