FIELD: polymer materials and ceramics.
SUBSTANCE: invention provides a novel method for preparing silicon carbide-based powder material suitable for manufacturing ceramic products. Material is prepared by mechanochemical treatment of organosilicon polymer for 10 to 90 min on planetary ball mill in inert atmosphere (pressure 1-5 atm), wherein 50-150 g grinding balls are used per 1 g polymer and acceleration of balls is 20-60 g. Preferably grinding balls are 3-12 mm in diameter.
EFFECT: facilitated powder preparation procedure, achieved powder particle size of the order of several nanometers, and increased yield of ceramics.
