GAS-PERMEABLE MEMBRANE FROM INORGANIC MATERIAL Russian patent published in 2009 - IPC B01D71/02 B82B1/00

Abstract RU 2345826 C1

FIELD: chemistry.

SUBSTANCE: proposed gas-permeable membrane from inorganic material consists of a porous substrate, made from graphite-like boron nitride, obtained during self-propagating high-temperature synthesis, and a selective layer based on mixed phosphorous and titanium oxides with general formula P_0.03Ti_0.97O₂ or based on mixed oxides and nitrides with general formula Al Si N₃O₃C₃P.

EFFECT: membrane has nano-structure properties with anisotropic effect, with non-symmetric gas transfer properties.
