Формирование поддержек Al2O3 экструзионной аддитивной технологией

Abstract

In this work, Al2O3 supports were obtained by extrusion additive technology with different subsequent annealing temperature. The microstructure was determined by scanning electron microscopy. Open porosity and apparent density were determined by hydrostatic weighing. Flexural strength was determined by three-point bending method. Optimum support permeability values of 8.8⋅10-8 mol(H2)/(m⋅s⋅Pa) are observed at a sintering temperature of 1250 °C. The thickness of the Pd membrane is 2.3 µm and the permeability values are 7⋅10-8 mol(H2)/(m⋅s⋅Pa0.5)
