内容简介

An investigation of the effects of various additives on the improvement of the spalling resistance of spherical magnesia porous brick gave the result that the addition of alumina and spinel gave a four-fold improvement in spalling resistance in comparison with spherical MgO porous brick without any additives. It is hopeful that the service life of porous plugs can be substantially increased by the use of additives.
