| 摘 要： | The effect of the admixtures of Al and Si metals and B4C and MgAlON compounds on the oxideation of MgO/Si3N4 composite refractory has been studied,which is a promising carbon free refractory for steel-making applicatlon.The four kinds of admixtures can be used as anti-oxidants for Si3N4,ut the mixture of Al and Si achieved the best result .The mixture can not only play the role as antioxidant,but also assist the sintering process and help form dense sintering layer,improving the property of the composite.

| Abstract: | The effect of the admixtures of Al and Si metals and B4 C and MgAlON compounds on the oxidation of MgO/ Si3N4 composite refractory has been studied, which is a promising carbon free refractory for steel-making application . The four kinds of admixtures can be used as anti-oxi-dants for Si3N4, but the mixture of Al and Si achieved the best result. The mixture can not only play the role as anti-oxidant, but also assist the sintering process and help form dense sintering layer, improving the property of the composite. |
