MgO-Cr2O3-ZrO2 bricks were prepared by impregnated MgO-Cr2O3 refractory into ZrOC12·8H2O solution in vacuum condition. Then the properties of MgO-Cr2O3-ZrO2 bricks were researched in this study. The results showed that the properties of the MgO-Cr2O3-ZrO2 bricks, such as bulk density, cold crushing strength, pore distribution, are superior to those of the MgO-Cr2O3 refractory. The ZrO2 introduced to MgO-Cr2O3-ZrO2 bricks by vacuum impregnation method were distributed in reunion in the aggregate and matrix combining site and cracks and pores of the matrix of MgO-Cr2O3-ZrO2 bricks, which can significantly refine internal stomatal aperture of the bricks. |
