摘要
Magnesia spinel refractory is a promising material because of its good properties at high temperature,good exfoliation-and coorosion-resistances,Three kinds of additives containing ZrO2 were added o magnesia spinel refacto-ries to get better exfoliation resistance,corrosion resistance and adhensiveness,Three kinds of ZrO2-containing additives added to optimize the properties of the material are particularly discussed in this paper.
