Description
Für atomtechnische Zwecke dienende Formkörper aus Kohlenstoff Zusatz zur Patentanmeldung G 8053 VIII c l21 g (Auslegeschrift 1021514) Gegenstand der Hauptpatentanmeldung sind kompakte Formkörper aus Kohlenstoff, die aus hochreinem kristallinem Schuppengraphit bestehen und vorzugswei@se zur Bremsung und Reflexion von Neutronen dienen.For atom technical purposes serving molded body of carbon addition to the patent application G 8053 VIII c l21 g (Auslegeschrift 1 021 514) the subject of the main patent application are compact shaped bodies made of carbon, which consist of highly pure crystalline flake graphite and vorzugswei @ se for braking and reflecting neutrons are used.
Die Erfindung betrifft -eine spezielle Ausführungsform der obengenannten Graphitkörper, die dadurch gekennzeichnet ist, daß die Zwischenräume zwischen den einzelnien Schuppen des als Ausgangsmaterial verwendeten Schuppengraphitpulvers entweder durch Ausfüllung mit einer Kittsubstanz aus verkohlten oder graphitierten Kohlenstoffverbindung:en oder aber durch verdichtende Pressung möglichst weitgehend beseitigt sind. Dies läßt sich beispielsweise folgendermaßen erreichen: 1. Pulverförmiger Schuppengraphit in hochreinem Zustande wird innt möglichst geringen Mengen eines kohlenstoffreichen Biindemittels wie Teer od. dgl. verrührt und pressend geformt, wobei die Graphitschuppen bei hinreichender Größe auch in paralleler Orientierung gelagert werden können. Anschließend wird das Bi,ndemittel durch Erhitzen des Formkörpers verkohlt oder graphitiert, ohne daß sich. wie im Beispiel 1 nach der Hauptpatentanmeldung, eine Schmnelzung der Kittsubstanz anschließt. Durchschnittliche Dichte der Kohlenstoffmasse: über 2.0.The invention relates to a specific embodiment of the above Graphite body, which is characterized in that the spaces between the individual flakes of flake graphite powder used as the starting material either by filling with a cement substance made of charred or graphitized Carbon compounds: or as much as possible by compressing pressure are eliminated. This can be achieved, for example, as follows: 1. In powder form Flake graphite in a highly pure state is used in the smallest possible quantities carbon-rich binding agent such as tar or the like, stirred and molded, the graphite flakes, if they are of sufficient size, also in a parallel orientation can be stored. Subsequently, the bonding agent is made by heating the shaped body charred or graphitized without becoming. as in example 1 after the main patent application, a melting of the cement substance follows. Average density of carbon mass: over 2.0.
2. Hochreiner pulverförmiger Schuppengraphit, geg elienenfalls in paralleler Orientierung, wird einem Druck von beispielsweise 3000 bis 5000 kg/cm= ausgesetzt, bei welchem eine weitgehende mechanische Verdichtung, aber noch nicht, wi,e im Beispiel 2 nach der Hauptpatentanmeldung, ein oberflächliches Fließen der Graphitteilchen stattfindet. Durch diese Pressung ergeben sich Graphitmassen mit einer Dichte von 2,1 bis 2.2.2. Highly pure powdery flake graphite, if necessary in parallel orientation, a pressure of, for example, 3000 to 5000 kg / cm = exposed, in which an extensive mechanical compression, but not yet, wi, e in example 2 according to the main patent application, a superficial flow of the Graphite particles takes place. This pressing results in graphite masses with a density of 2.1 to 2.2.
Wenn die Formkörper (Platten. Ziegel, Würfel od. dgl.) aus parallel arienti,erten Graphitschuppen hestehen, lassen sie sich wie beim Gegenstand der Hauptpatentanineldung auch zur Ausübung voll Richteffekten auf Neutronen verwenden.If the shaped bodies (plates. Bricks, cubes or the like) are made of parallel arienti, erten graphite flakes stand, they can be as with the subject of the Also use the main patent application to exercise full directional effects on neutrons.
