Definitions

  • Ceramic membranes offer a higher thermal, chemical, and mechanical stability than polymeric membranes presently dominating in industrial practice.
  • Ceramic membranes with pore sizes in the nanometer range are obtained by slip- casting with a pore diameter of approximately 2 nm as the lower limit.
  • Figure 12 An "empirical" figure showing the normally observed correlation between precursor loading in a particle synthesis unit and the resulting morphology. Small concentrations result in very small, compact particles whereas an increase in concentration results in an increase in particle size and at even higher concentration aggregates of primary particles are formed (because there is insufficient residence time to sinter/coalesce the aggregate into a compact spherical particle).
  • Figure 15 The three figures (left column) illustrate the build-up of a layer in the pore mouths of and on the surface of a substrate during a dynamic deposition experiment in which the particle size gradually decreases with time.
  • the fairly coarse nanoparticles close the pore mouth of the substrate. Somewhat finer nanoparticles are deposited between the coarser nanoparticles in the pore mouth, and very fine nanoparticles are deposited on top and between the somewhat finer particles whereby an outer layer of nanoparticles are build on the surface of the substrate.
  • the deposition rate mass per time
  • a continuous reduction of the particle size can be obtained by continuously lowering the temperature in the saturator.
  • the diagram (right hand side) illustrates the continuous reduction in particle diameter.
  • the mixture of feed gases is fed to the burner through the swirl mixer to ensure high degree of mixing of fuel, oxidant and precursor.
  • the combustion of fuel takes place just above the flame arrestor, which is a thick (0.5-1 cm) metal plate with small cylindrical holes.
  • the flame arrestor distributes the flow of the feed gases and prevents flashback of the flame front.
  • the precursor is added to the flame as a vapour in a gas (e.g. nitrogen) stream from saturator unit that consists of a metal box with one or more metal trays on which thin layers of the precursor powder are in contact with the nitrogen stream.
  • the precursor has a certain sublimation pressure, which combined with the control of the heating element of the unit determines the concentration of the precursor in the carrier gas.
  • the aerosol phase of nanoparticles is prepared by the heating in a hot plasma of a gas mixture or aerosol containing desired precursor metals either present as evaporated molecules or as small droplets of precursors dissolved in a solvent (e.g. metal nitrates in aqueous solution or metal alkoxides in organic solvent).
  • a solvent e.g. metal nitrates in aqueous solution or metal alkoxides in organic solvent.
  • F is called the permeance and has the same unit as a diffusion coefficient and is defined as follows:
  • the permeability of H 2 , He and N 2 for the top layer hardly changes with the trans-membrane pressure difference also showing that the transport of gases through the top layer is controlled by the Knudsen diffusion mechanism.
