Abstract

Evaporation of aluminum under argon pressures of from 2-12 microns yields a porous aluminum deposit. SEM (scanning electron microscope) examination reveals a matrix of aluminum composed of columnar aluminum growths standing on end with cross-communication among them. The degree of porosity increases with increasing argon pressure. Deposits have been grown to a thickness of 7 mum.

Forming Porous Aluminum

Evaporation of aluminum under argon pressures of from 2-12 microns yields a porous aluminum deposit. SEM (scanning electron microscope) examination reveals a matrix of aluminum composed of columnar aluminum growths standing on end with cross-communication among them. The degree of porosity increases with increasing argon pressure. Deposits have been grown to a thickness of 7 mum.

Other gases than argon may be employed, and other vacuum deposition techniques, such as sputtering (e.g., at a pressure of 40 microns), can be used to produce porous aluminum.
