Abstract:

An electric-arc plasma instalation operated in the hidden anode arrngement is constructed and used for the pereparation of carbon nanostructures. A device and a method were developed to produce nanomaterials in the form of nano-particles that are stable, polymorphic, head modified crystal structures of any type of elecrtically conducting materials, in particular of graphite, and possess unique physical, chemical and mechanical properties. The operating technological parameters of the contracted plasma arc were deternined in view of obtaining nanosised carbon structures withe given shape (nano-tubes, fullerenes,clusters,disc-like shapes,leaf-shaped etc.), size and structure. The method, the divice and the nanomaterials produced can find application in the plasma-chemical industry, the nanotechnologies, the space technologies, the medicine and for fabrication of composite materials.
