Disclosed herein is a porous membrane comprising a porous substrate; a porous ceramic coating disposed on the porous substrate; where an average pore size of pores in the porous substrate are larger than an average pore size of pores in the porous coating. Disclosed herein is a method of manufacturing a porous membrane comprising disposing upon a porous substrate a porous ceramic coating, where the porous ceramic coating has an average pore size that is less than an average pore size of the porous substrate.

Engineered coating for filters and methods of manufacture thereof

Disclosed herein is a dual density disc comprising a dense outer tube comprising alumina having a purity of greater than 99%; and a porous core comprising alumina of a lower density than a density of the dense outer tube; wherein the porous core has an alumina purity of greater than 99%. Disclosed herein too is method comprising disposing in a dense outer tube a slurry comprising alumina powder and a pore former; heating the dense outer tube with the slurry disposed therein to a temperature of 300 to 600° C. to activate the pore former; creating a porous core in the dense outer tube; and sintering the dense outer tube with the porous core at a temperature of 800 to 2000° C. in one or more stages.
