  The diamond-SiC composite has a low density and the highest possible speed of
sound among existing materials except for the diamond. The composite is
synthesized by a complex exothermic chemical reaction between diamond powder
and liquid Si. This makes it an ideal material for protection against impact
loading. Experiments show that a system of patterns is formed at the
diamond-SiC interface. Modeling of reaction-diffusion processes of composite
synthesis proves a formation of ceramic materials with a regular (periodic)
interconnected microstructure in a given system. Composite material with
interconnected structures at the interface has very high mechanical properties
and resistance to impact since its fractioning is intercrystallite.
