Abstract

The results of a comprehensive study of the material composition and structural and morphological characteristics of two types of high-alumina matrix systems, obtained entirely on the basis of domestic components - high-alumina highly concentrated suspension of ceramic binder (HCBS) and suspension based on reactive alumina (RA), are presented. The objects of study are four samples of experimental high-alumina matrix systems (HMS), comparable in particle size distribution. According to the results of X-ray phase analysis, HMS based on reactive alumina are characterized by the content of the α-Al2O3 phase of more than 99%, while the samples of HCBS are polyphase with a predominance of mullite, alpha-alumina and quartz in the mineral complex. The nature of the distribution of particles in the studied samples is different: both mondomodal HMS with a narrow distribution of particles and a median size of about 0.8 µm, and bimodal HMS with a median size of 4 µm or more are presented. The content of the submicron fraction (particle size less than 1 micron) varies from 10-15% to 60%. Using scanning electron microscopy, the features of the microstructure were revealed and the morphology of the particles of the solid phase of HMS of both types is studied in detail. Using X-ray microanalysis, the chemical (elemental) composition of the studied materials is established.
