<P>PROBLEM TO BE SOLVED: To enhance durability greatly by drastically improving the weak point, that is, poor resistance to slag infiltration, of conventional magnesia chrome bricks. <P>SOLUTION: The magnesia chrome bricks with an improved resistance to slag infiltration can be prepared by impregnating magnesia chrome bricks with a solution, which is prepared by dissolving a chrome (III) salt in a state of chrome ions into a solution such as water, in order to impregnate uniformly into small holes inside the bricks and by heating after the above process to decompose chrome (III) salt and to generate chrome oxide (Eskolaite). Namely, by the manufacturing method, magnesia chrome bricks are impregnated with a solution, where chrome (III) salt is dissolved, in order to incorporate a chrome (III) salt in a brick structure. <P>COPYRIGHT: (C)2007,JPO&INPIT |
