FIELD: chemistry.
SUBSTANCE: invention relates to inorganic chemistry and can be used in making catalyst supports, filters and electronic materials. The starting materials used are powdered silicon and detonation synthesis diamonds, which are mixed in weight ratio silicon:diamond from 2:1 to 2.4:1. The powdered mixture is then moulded into a workpiece of the required article and then heat treated at temperature of 1200-1500°C in a vacuum or inert medium.
EFFECT: invention enables to obtain nanostructured silicon carbide in form of articles having high porosity - 55-65 vol. % and simultaneously sufficient strength, wherein the size of crystalline regions is in the range of 10-50 nm.
