    Corrosion resistance of ultra-high purity porous alumina

    In this work, an ultra-high purity porous alumina ceramic support was prepared by the boehmite-coated alumina powders. Its corrosion resistance in 20 wt% H 2 SO 4 and 10 wt% NaOH hot aqueous solutions (80 °C) for 2 to 8 h was investigated. It is demonstrated that the high-purity support has excellent corrosion resistance.
