ABSTRACT:

The production and properties of polycrystalline metal whiskers, their processing and some examples of application as heat exchangers, catalysts or catalyst carriers, catalysts for the Fischer-Tropsch synthesis, and other applications are discussed. A metal carbonyl such as iron or nickel is produced by thermal decomposition in a magnetic field. The needle shaped whiskers are marked by great mechanical and thermal stability. In contrast to monocrystalline whiskers they can be produced rapidly and in great quantity.
