dos tijolos refratários de magnésia-carbono de uma panela de aciaria, devido ao ataque da escória SiO2-CaO-Al2O3-MgO. Para tanto, tijolos refratários MgO-C utilizados na linha de escória de uma panela industrial foram comparados com tijolos após o uso (post mortem). A microestrutura da região interfacial escória / refratário foi avaliada por análises mineralógicas (difração de raios X), microscopia eletrônica de varredura e microscopia óptica (lâminas petrográficas). Foi possível constatar que o tijolo post mortem apresenta, além das fases já existentes in natura, novas fases como a alumina, o silicato de cálcio e a gelenita devido à sua reação com a escória. Os resultados sugerem que o principal meio de degradação do tijolo se estabeleça p...
