Refractory bricks consisting essentially of MgO (periclase) with about 15 percent of other oxides. Magnesia brick are used wherever the corrosion of basic slags is severe, as for almost the whole of open-hearth steel furnaces, of copper reverberatory furnaces, in soaking pits and in the basic electric steel furnace.Certain factors tend to reduce their application, including higher cost, comparitively lower mechanical strength at elevated temperature and greater thermal expansion.
