Abstract

The patterns of vesiculation in hydrosilicates are considered in the paper. The main objective is obtaining overall dependencies of vesiculation in the intumescent material based on silica to develop a strategy of production of heat-insulating materials with a structure close to optimal. General regularities of porous structure formation in foam mass with various chemical components are given. General conclusions on the influence of impurities in the initial mass on the process of material intumescence are made. It was also concluded that the change in the local moisture content does not affect the overall vesiculation process, since the rate of moisture diffusion in the material exceeds the vesiculation rate. In addition, a series of experiments on the effect of aluminium on the vesiculation of alumina material was carried out. Small additives of aluminium increase the strength characteristics and porosity in siliceous mass with small amounts of impurities.

The results can be of interest to scientists and engineers dealing with the production of refractory materials.
