Abstract: 
Three different materials (aluminum, ferro-silicon and silicon ) were used as ‎antioxidants in order to prevent the decarburization process and to keep and/or ‎increase the final properties in MgO-C refractories. Their effects were compared by ‎measuring the physical and mechanical properties as well as oxidation and the ‎resultant phases and microstructures, in the temperature range of 200-1600°C. High ‎temperature oxidation was measured up to 1000°C. The impurities of the aluminum ‎and silicon powders were less than 1%. The ferro-silicon contains 2-5% Al, and 10-‎‎20% Fe. Results indicate that the oxidation of the samples were much better in the ‎ferrosilicon that aluminum and silicon case. The CCS measurements indicate more ‎improvements due to the effects of ferro-silicon than silicon case. Results indicate that ‎aluminum is more effective at low temperature. However, at higher temperatures, the ‎other two anti-oxidants are more effective. The phase analysis indicates that the ‎reaction of M__2S phase with other phases might cause some reduction of high ‎temperature behaviors. Also, phase analysis indicates the formation of MgO-‎FeO/Fe__2O__3 phase, aluminum and silicon carbides as well as Spinel phase in the ‎samples‏.‏
