Metal/Carbon Composites KLASTA MATE™

klastamate1.jpgIntroducing KLASTA MATE™, a metal-carbon composite combining a desired concentration of metal with carbon.

KLASTA MATE™ is a composite material combining metal and carbon. Its structure consists of metal particles dispersed homogeneously through a carbon material. KLASTA MATE is notable as it can be constructed by combining a required metal at a required concentration with carbon. It can be used with the majority of metals on the periodic table. It can also be made from a combination of two or more types of metal. KLASTA MATE™ is used as a raw material for combining nanocarbons typified by metallofullerenes and carbon nanotubes. Using it as a sputtering target and evaporation source for arc ion plating, makes it also suitable for forming diamond-like carbon (DLC) films doped with metal elements.
