METHOD OF OBTAINING CERAMIC COMPOSITE WITH A MULTICHANNEL STRUCTURE Russian patent published in 2017 - IPC C04B35/565 C04B35/58 C04B35/65 

FIELD: chemistry.

SUBSTANCE: according to the mode of obtaining ceramic matrix composite based on Ti₃SiC₂, reactionary composition made up of long titanium elements (inserts) in the form of rods or tubes, arranged in a regular manner, and ceramic silicon carbide-based mass that fills the space between the titanium elements, heat-treated in non-oxidizing conditions, at 1350-1500°C. Used ceramic mass contains silicon carbide as a main component, carbon additives and/or titanium carbide, as well as temporary technological bunch from organic polymer ensures precalcination strength.

EFFECT: possibility of obtaining ceramic composites with matrix based on Ti₃SiC₂ having a regular system long isolated hollow channels, using the method of inverse replicas, which conduct heat treatment at a temperature significantly blanks source below the melting temperature of the metal inserts.
