Abstract
In one embodiment, the present invention may be a method of making a porous biocompatible metal article by combining a metal powder with a homogenizing aid to form metal granules, including blending the metal granules and an extractable particulate to form a composite, forming the composite into a green article, removing the extractable particulate from the green article to form a metal matrix and pore structure, and sintering the metal matrix and pore structure. Furthermore the present invention may include a second homogenizing aid combined with the extractable particulate. The present invention also includes shaping the metal matrix and pore structure with or without the use of a binder.
