摘　　要：The effect of electric fused ZrO2,m-ZrO2 and zirconite on the sintering properties of MgO-CaO bricks was studied and the effect of the ZrO2 content and temperature on BD （bulk density）, AP（apparent porosity）and CCS （Cold Crushing strength） of MgO-CaO bricks was investigated.The microstructure of burned specimens was analyzed by SEM. The result shows that the sintering property is best while 5% m-ZrO2 was added at 1 600 ℃.The effect of electric fused ZrO2,m-ZrO2 and zirconite on the sintering properties of MgO-CaO bricks was studied and the effect of the ZrO2 content and temperature on BD （bulk density）, AP（apparent porosity）and CCS （Cold Crushing strength） of MgO-CaO bricks was investigated.The microstructure of burned specimens was analyzed by SEM.
