Investigation on the alkali resistance property of theoretical composition magnesia alumina spinel bricks

摘要：

　　Using alumina-rich MgAl2O4 spinel AR78 and 97 fused magnesite as mw materials,brine as the binder,magnesia alumina spinel bricks close to theoretical composition have been prepared.The phase composition and microstructure of the specimens were analyzed and characterized.The alkali resistance property of specimens was researched using static crucible method.The erosion mechanism of alkali vapor to specimens was studied by XRD,SEM and EDS.The results show that:(1) The alkali resistance property of MgAl2O4 spinel bricks were improved obviously when the addition of magnesite is more than 7%.(2) The alkali resistance property of MgAl2O4 spinel bricks is the best when the addition of magnesite is 10.3%.
