The formation of silicon carbide with high porosity parameters is favored by the use of the KIT-6 mesoporous molecular sieve (MMS) with a three-dimensional structure and a mutually intersecting system of mesopores as matrix, by the close to the stoichiometric C/SiO2 ratio, and also by the higher level of filling with carbon in the pores of the siliceous MMS.
