Abstract
Described herein is a cordierite membrane coated on a monolith substrate formed from cordierite. The membrane coating is formed from cordierite particles which have been processed to have a median particle size diameter of between 1 and 3 microns with a narrow particle size distribution suitable for forming a cordierite membrane on a cordierite monolith substrate. After the cordierite membrane is formed on the cordierite monolith substrate, the cordierite membrane monolith has a pore size of less than 1 micron.

A cordierite membrane monolith comprising:
- a cordierite monolith substrate;
- a cordierite membrane on a surface of the cordierite monolith substrate forming a cordierite membrane monolith;
- wherein the cordierite membrane monolith has a median pore size of less than 1 μm.
A method of making a cordierite membrane monolith comprising applying a slurry of cordierite particles having a median particle size of between 1 and 4 μm to a cordierite monolith substrate.
