Crystalline copper

Single Crystal Copper (Crystalline Copper) is a subtype of high purity copper metals. Other types include electrolytic copper, which however does not achieve same purity values as crystalline copper.

Properties

Crystalline copper features a single crystal structure, which comes from the fact that it is grown using the Czochralski process. Crystalline copper, grown as a single crystal, has unique physical and chemical properties, such as considerably longer granules and absolute absence of gaseous impurities such as oxygen, carbon, hydrogen and nitrogen.

The Ohno Continuous Casting (OCC) process [ [http://www.musicpoint.nl/Furutech/furutech_occ.htm Furutech] , Manufacturer of Pure Copper by Ohno Continuous casting, retrieved October 1, 2006 ] may also be used to obtain longer than usual granules, yet granules are much shorter than in single crystal copper.
