| Summary: | Title screen In this work, preceramic paper-derived porous Al2O3 ceramics were fabricated by spark plasma sintering at 1200–1400 °C and 10 MPa pressure. The microstructure and phase composition of the formed materials were investigated. The porosity, apparent density, bending strength and gas permeability of the obtained materials were also evaluated. The increase in sintering temperature from 1200 to 1400 °C results in densification and strengthening of Al2O3, but reducing its gas permeability. The bending strength was 16 and 33 MPa for the Al2O3 supports fabricated at 1300 and 1400 °C, respectively. Palladium membranes have been formed by chemical deposition on the obtained Al2O3 supports. The hydrogen permeability and hydrogen flux of 4.2 μm-thick Pd membrane on Al2O3 support were 4·10−9 mol(H2)/(m∙s∙Pa0.5) and 0.67 mol(H2)/(m2∙s), respectively Текстовый файл AM_Agreement |
