Interfacial spinellisation of MgO–C/Al2O3–C composite
In addition M Emmel found that carbon hinders the formation of spinel in carbon containing refractories The presence of carbon not only limits the contact between MgO and Al 2 O 3 but also limits the mutual diffusion of Mg 2 and Al 3 thereby reducing the in situ formation of MA However the partial pressure of Mg g is higher under non oxidising atmospheres and this characteristic affords

Carbon in the form of graphite is commonly used in refractories for metallurgical purposes because of its ability to increase resistance to corrosion However if the graphite in the refractory becomes oxidized it greatly loses this ability For this reason it is very important for a refractory to have good resistance to oxidation but there are at present no refractories fully satisfactory
