After the advent of powder nanotechnologies, there has been a unique opportunity to sinter high-density silicon carbide ceramics within the framework of ceramic technology. The relatively low density and ability to withstand substantial thermal and mechanical overloads makes it attractive for producing of a heat exchanger for SOFC. 
The unique laboratory technology for production of ceramic products from SiC for aviation applications has been developed. The commercial SiC nanopowders manufactured by SikaTech, having a particle size of 40 nm and a specific surface area of 16 m2 / g.  A unique technology for production of laboratory ceramic products from SiC for energy applications has been developed. 
 Standard ceramic technology was used. The products were manufactured by sintering at a temperature of 2080 ° C in an induction furnace RFI-25 in an inert atmosphere. A hydrostatic pressure of 200MPa was used at forming the bulk samples. Technical tests showed a very high resistance of the products to thermal cycling.
