Abstract :

Mgo-C refractories due to suitable properties which mainly related to presence of graphite and Carbon bonding are widely used in steel industry. The most disadvantages of these type of refractories is lack of bonding at high temperature. In the present work tried to investigate nitride bonding formation and effect on physical, mechanical properties, phase analysis and microstructure of samples. Result showed that because of presence of forsterite and silicon nitride together thermomechanical properties could be improved.
