Cordierite-based composite membrane coated on cordierite monolith

Composite-membrane monoliths include a cordierite monolith having a cordierite-ceramic composite membrane bonded to surfaces thereof with a surface median pore size. The cordierite-ceramic composite membrane has membrane surfaces with a membrane median pore size of 0.3 μm or less. The cordierite-cer...

Beschreibung
Zusammenfassung:	Composite-membrane monoliths include a cordierite monolith having a cordierite-ceramic composite membrane bonded to surfaces thereof with a surface median pore size. The cordierite-ceramic composite membrane has membrane surfaces with a membrane median pore size of 0.3 μm or less. The cordierite-ceramic composite membrane may be a composite formed by firing the cordierite monolith subsequent to applying a cordierite-ceramic composite slip to surfaces thereof. The cordierite-ceramic slip may include cordierite particles and ceramic particles. The cordierite particles may have a cordierite median particle size smaller than the surface median pore size. The ceramic particles may have a ceramic median particle size smaller than the cordierite median particle size.
