The principal merit of the developed technology is the fact that the combustion synthesis yields a sintered matrix of the desired shape (hollow cylinders or spheres, plates), pore structure, and phase and chemical composition, which could be used without any additional processing. To obtain the synthesized materials with desirable macroporous structure a special mode of propagation of the combustion wave was considered. The front of combustion wave here consists of many separate superadiabatic spots. There
