    Al2O3 Ceramic Foam Filtration Boards

    Al2O3 ceramic foam filtration boards are produced by adopting high quality alumina as the main raw material, a special shaping method, and high tempearture calcining. They are mainly used for filtration and impurity-removing of Al or Al alloy molten liquid with good filtration precision and flow stabilizing effect. 

    Main Features:

    • High quality alumina of main raw material, high strength, and precise dimensions. 
    • Maximum service temperature of 1200℃ and long service life
    • High through pore rate, few blocked pores, no spalling
    • Good erosion resistance to Al liquid and excellent hot properties
