A method for the production of metals mesophases - pitches and metals graphitizable carbon fibers, that is mesophases - pitch, graphitizable mesophases - pitch-coated fibers and composition for the production of carbon - artifacts

摘要

it is an improved method for the production of a unique, metal containing, anisotropic bad luck is described, which is for the manufacture of carbon fibres.the soluble, aromatic - certain organometallic compounds to a carbonaceous feedstock as it essentially free of mesophasen pitch, and the obtained composition is used to produce a mesogene and soluble, aromatic metal organic compounds e nthaltenden, isotropen pechprodukts heat-treated.subsequently, the pechprodukt a lu00f6sungsmittelfraktionierung process in order to separate the mesogene, mteall of the organometallic compounds. the metal containing mesogene are then heated to a temperature which is sufficient to achieve a fusion of the mesogene and a metal containing mesophasen pitch to produce.$a in another method, the carbonaceous feedstock is heat-treated, a mesogene containing isotropes pechprodukt to produce, and it will be the mesogen containing isotropen pechprodukt before the lu00f6sungsmittelfraktionierung soluble, aromatic metal organic compounds an high molecular weight added.the mesophasen pitch produced, metal containing carbon fibres exhibit improved stability, zugfestigkeits and zugmoduleigenschaften. $a alternatively, the lu00f6sungsmittelfraktionierung or the separation of critical...
