Self Bonded Silicon Nitride Bonded Silicon Carbide Brick Sicatec95 for Aluminum Electrolysis Cells

    The silicon nitride bonded silicon carbide bricks are prepared using high gradesilicon carbide and industrial silicon powder as starting materials, shaping byvibration pressing and firing by step high pressure nitridation sintering. Theyare characterized by good corrosion resistance to cryolite, good oxidationresistance, high hot strength, good thermal conductivity and long campaign life.They are ideal side wall materials for large prebaked aluminum electrolysiscells over 180 kVA. Compared with side carbon blocks, the bricks are more energy-saving.
