SYNTHESIS OF HIGH-STRENGTH CERAMICS BASED ON TECHNOGENIC WASTE CONTAINING ALUMINUM OXIDE

Abstract

The aim of this work is to synthesize wear-resistant and heat-resistant ceramics based on aluminum oxide. The manmade aluminum-containing waste of the Shurtan gas chemical complex was used as a source of aluminum oxide. In the work, the dependences «composition-structure», «composition-property» and «property-size of particles» were obtained, obtained by the method of heliomaterials science, namely by melting raw materials in a stream of concentrated solar radiation of high density (350 W/cm2) with subsequent quenching of the melt into water (103 deg/s). It is shown that the wear resistance and heat resistance of the material sharply increase when the content in the mass is more than 80% of aluminum oxide.
