2006-1-1u2002·u2002Spinel is used as an additive in magnesia rich bricks, for example for cement kiln linings. Magnesia rich spinel bricks are used in the cooling zone and in the upper side of the sintering zone of the cement kiln. 3, 4 In addition, spinel particles are added in various proportions to MgO in order to improve its thermal shock resistance. Magnesia–spinel materials give significantly (two to ...
