It is established that the main process of mass transfer during the course of physicochemical interaction with the formation of titanium diboride and graphite is the diffusion transport of boron through the gas phase, which begins by irreversible sublimation of its atoms from the surface of B4C and ends with their precipitation on all free surfaces of grains TіС.
