| ABSTRACT |
|
The effect of additives on properties of unfired Al2O3-C bricks were investigated. The increase of carbon content and the addition of MgO or spinel improved the resistances against spalling and corrosion of unfired Al2O3-C bricks. Also, the oxidation resistance of unfired Al2O3-C brick was increased by adopting complex metals of Al and Si in spite of the increase of carbon content. |
