ABSTRACT:
A filter membrane and a process for making the filter membrane are provided. The filter membrane comprises a metal substrate having a filtering layer thereon comprising sintered ultra-fine particles of metal or ceramic compounds. The filtering layer preferably has an average pore size of from about 30 nanometers to about 200 nanometers. The filter membranes can withstand pressure drops of up to about 0.6 MPa and are useful for a variety of filtering applications.
