| Abstract Scope |
The formation of samples of SiC fraction 30-40 μm was performed with the addition of 12% oil coke and nanopowders SiC, Cr2C3 with a specific surface area of ~ 40 m2/g in an amount of 1% to 8%. Sintering of the formed samples was performed in vacuum at 2000-2100 0C for 30 minutes. The density without nanosized additives was obtained at the level of 3.04-3.06 g/cm3. For samples with SiC nanoadditives density at the level of 2.5-2.6 g/cm3 was obtained at a content of 4-5% nanopowders and an increase of almost 3.1 g/cm3 at a content of 7% additives. For samples with Cr2C3, first at 2-3% of the additive there is an increase in density, followed by a decrease in density with a local peak at 7%. A significant decrease in the electrical resistance of SiC - Cr2C3 samples at a content of 3% Cr2C3 nanopowder was found. |
