| Abstract: | In order to further improve the physical properties of MgO- C bricks, nanoscale carbon black was added into phenolic resin; the effects of adding certain amount of nanometer carbon black on the mechanical properties and thermal shock resistance of MgO- C bricks were studied. The test results reveal that the mechanical properties and thermal shock resistance of MgO- C bricks were increased with the addition of nanometer carbon black. And the best complex mechanical properties of MgO- C bricks were obtained when 5% (percentage of quality in resin) nanometer carbon black was added. |
