Production of Multichannel Ceramics Based on Ti3SiC2

A multichannel ceramic based on Ti3SiC2 was prepared using reactive composites consisting of regularly placed Ti rods and a silicon carbide ceramic matrix filling the space between them. The physicochemical formation mechanism of the multichannel structure of the obtained ceramic was studied. The key step was the reaction at 1360 – 1370°C that resulted in extensive melting of the Ti components followed by infiltration of the silicon carbide ceramic matrix by the resulting melt. Hollow channels formed in place of the starting Ti rods.
