Al 2 O 3 hollow fibre membranes were prepared by a combined phase-inversion and sintering method. An organic binder solution (dope) containing suspended aluminium oxide (Al 2 O 3 ) powders, either in mono size or a distributed size, is spun to a hollow fibre precursor, which is then sintered at elevated temperatures. In spinning the hollow fibre precursor, polyethersulfone...
Strontium cerates-based ceramic powders, SrCe 1-x M x O 3-α (x=0.05, M=Yb, Y, In, Ga, La) containing a single perovskite phase have been synthesized via water-soluble complex precursor routes using ethylenediaminetetraacetic acid (EDTA), citric acid or glycine as a chelating ligand. The effects of the chelating agent on the synthesis and the evolution of...
