|
| Electrovac is Austria’s sole producer of carbon nanofibers (CNF) and holds relevant patents for the production of such nanofibers (filiform graphite tubes with a diameter of a few nanometers: 1nm = one millionth of a millimeter). |

|
| Production |
|
|
|
| If gaseous carbon (from hydrocarbon, i.e. natural gas) is deposited on heated metallic particles, tube-shaped, graphite-like structures (CNF) develop from these particles. This production is known as Catalytic Chemical Vapor Deposition method (CCVD method) which is equivalent to catalytic deposition from the gaseous phase. This outstanding graphitic structure is inherent in carbon nanofibers and enables their utilization as |

and / or thermal |

|
|
reinforcements in compound materials.
They can also be used at field emission peaks in monitor applications, as catalyst supports, or as electrode material in batteries. The latter application is currently not being actively developed by Electrovac. |

|
| Fillers |
|
|
|
| Owing to their outstanding physical and multifunctional properties, already minimal amounts of CNF are highly suitable for utilization as functional filling materials, i.e. in polymers; especially in thermoplasts and duroplasts carbon nanofibers are applied today to meet the requirements of present and future applications. |
