Obtaining multichannel ceramics based on Ti3SiC2

It has been proposed to use reaction compositions for producing Ti3SiC2-based multichannel ceramics made up of regularly laid titanium rods and a silicon carbide ceramic material filling the space between the titanium rods. The physicochemical mechanism of formation of the multichannel structure of the resulting ceramic material has been studied. The key stage of the process is the reaction at 1360--1370 °C, as a result of which intense melting of titanium components occurs and subsequent infiltration of the silicon carbide ceramic mass with the resulting melt. In place of the original titanium elements hollow channels are formed.
