Abstract
Porous anodic aluminum oxide sheet, when removed from its aluminum metal substrate, is a useful filter but rather brittle. It can be formed into a desired shape by flexing in a direction transverse to the direction in which the metal substrate was rolled. Or the sheet can be wetted to make it more flexible and then formed by flexing in any direction. The formed sheet can be heat-set in a desired shape by heating at 200.degree. C. to 650.degree. C.
