SiAlON Bonded SiC Bricks

    SiAlONbonded SiC bricks are produced using high quality silicon carbide, industrialsilicon powder and alumina powder as starting materials, firing at about 1 500 by the nitridation solid solution reaction. Compared with Si3N4bonded SiC products, the SiAlON bonded SiC bricks are characterized by good resistanceto alkali corrosion slag and oxidation. The bricks are mainly used in the lowerpart of stack, belly and bosh of BF. The bricks were awarded the “The ThirdPrize of National Science & Technology Progress” in 1998 and have been appliedsuccessfully in BF of Anshan Steel and Zhangjiagang Steel, etc.
