| 摘要 |
A new article of manufacture consisting of a crystal of copper which is macrocrystalline, unicrystalline, columnar and consists of a single prime particle bounded by at least two sets of distinguishable planes which are determined by the internal crystal structure. These planes are cube faces, i.e., (100) type planes in the crystal and define surface facets which are parallel, non-coplanar, crystallographic step-growth surfaces. The crystal orientation is such that a (110) plane is perpendicular to the long axis of the crystal with a (111) plane lying perpendicular to the smallest cross-section thereof. |
