Abstract

Silicon carbide (SiC) microfiltration membranes were fabricated via dip-coating on tubular SiC supports with an average pore size of 1.4μm with SiC powder (the average particle size of 0.8μm) as a raw material and PMAA-NH₄ as a dispersant. The effects of pH value and dispersant amount on the stability of SiC suspensions, as well as the effects of sintering temperature and atmosphere (i. e., Air, Ar and N₂) on the properties of SiC microfiltration membranes were investigated. The results show that the stable slurry can be obtained when pH value is 10 and PMAA-NH₄ amount is 0.6% (in mass fraction). The SiC microfiltration membrane sintered in N₂ at 1200℃shows the optimized performance (i. e., the average pore size of 78nm, the membrane thickness of 10μm and the pure water permeability of 860L•m^-2•h^-1•bar^-1).
