Ceramics Based on Nano-Modified Alumino-Silicates

Abstract:

The paper considers the formulation of nanomodification of alumino-silicate raw materials, in order to obtain ceramic materials, based on it, by various molding methods with an increased strength and other operational properties. Studies of the dependence of the compressive strength on the type and concentration of aluminum and silicon oxide nanoparticles, their influence on the granulo-metric composition and microstructure of alumino-silicate powders, based on alkaline earth bentonite, are presented. It is shown that the addition of oxide nanoparticles in small concentrations leads to a decrease in the average particle size, aggregated structural elements of bentonite and their redistribution, and changes in morphological parameters (the shape of micro-aggregates and aggregates, pores), which increases the strength of raw materials and, as a result, burnt products.
