MAGNESIA/CARBON BRICK AND PRODUCTION METHOD THEREOF
PROBLEM TO BE SOLVED: To provide magnesia/carbon brick having excellent binding properties between carbon fibers and magnesia fine particles for improving the thermal shock resistance of the brick and a production method thereof.SOLUTION: In a first embodiment, the magnesia/carbon brick containing a magnesia raw material and a carbon raw material is provided that uses, as a carbon fiber contained in the carbon raw material, a carbon fiber coated with magnesia fine particles obtained by an electrostatic alternate adsorption method on the surface thereof. In a second embodiment, the magnesia/carbon brick is provided that is identical to the magnesia/carbon brick in the first embodiment except that 1 to 5 mass% of the carbon fiber coated with magnesia fine particles is added to an entire brick of 100 mass%. In a third embodiment, the magnesia/carbon brick is provided that is identical to the magnesia/carbon bricks in the first and the second embodiments except that 70 to 95 mass% of magnesia raw material and 5 to 30 mass% of the carbon raw material containing the carbon fiber coated with magnesia fine particles are added to the entire brick of 100 mass%.SELECTED DRAWING: Figure 1
