ABSTRACT:
A separation membrane includes a glassy microporous membrane and a ceramic porous support. The separation membrane has excellent heat resistance, corrosion resistance, durability, gas-separability and high mechanical strength. The separation membrane is preferably provided with a metallic or ceramic microporous membrane vapor-deposited on the surface of the glassy microporous membrane. The separation membrane can be utilized with high efficiency in diversified fields such as microfiltration or ultrafiltration of liquidal or gaseous fluids. A process for manufacturing such a separation membrane is also disclosed.
