چکیده انگلیسی
The dispersion and the stability of the suspensions from commercially available 8 mol.% yttria stabilized zirconia (8YSZ) powder have been systematically investigated as a function of the system factors such as pH value, temperature, solid loadings, molecular weight and amounts of polyacrylic acid (PAA) dispersant. The interaction mechanisms between YSZ particles and organic additives in suspensions were analyzed and discussed in detail. The crack-free tubular membranes derived from the fully dispersed and well stabilized YSZ suspensions with appropriate viscosity exhibited an average pore diameter of 0.31 μm and membranes thickness of 10 μm. The pure water permeability of the membrane was up to 1.7 m3 h−1 bar−1 m−2.
