SILICON STRUCTURE

摘要

A method for fabricating a macroporous silicon material comprises consolidation of particulate silicon. The particulate silicon may treated with hydrofluoric acid prior to the consolidation step. A uniaxial pressure of between 1,000 and 5,000 psi (6895-34470 kPa) is then applied by means of a cold pressing device (1). The consolidated product may be anodised to form further, smaller micropores within the material. The material may be used in the body for repairing of replacing bone. The consolidated silicon material may be crushed to form a partially surface porous silicon.
