Description

Darstellung von Berylliummetall. Entzündet man ein Gemisch von äquivalenten Mengen vom Berylliumoxyd mit Elementen von höherer Verbrennungswärme (Aluminium, Kalzium u..dgl.), so brennt dieses Gemisch zwar unter Wärmeentwickelung und unter Bildung von metallischem Beryllium ab, die Wärmeentwickelung ist jedoch nicht genügend, um das entstandene Gemisch von Berylliummetall und Aluminiumoxyd zum Schmelzen zu bringen. Es gelingt daher auf diese Weise nicht, eine regulinische Metallabscheidung zu erhalten.Representation of beryllium metal. Ignite a mixture of equivalents Amounts of beryllium oxide with elements of higher heat of combustion (aluminum, Calcium and the like), this mixture burns with the development of heat and under Formation of metallic beryllium, but the generation of heat is not sufficient, to melt the resulting mixture of beryllium metal and aluminum oxide bring. It is therefore not possible to achieve regular metal deposition in this way to obtain.

Nun setzte man zwar bereits den Reaktionsmischungen aus den Oxyden schwerer schmelzbarer Elemente und Aluminiumpulver Chlorate, Perchlorate, Superoxyde, Persulfate zu. Man beobachtete aber dabei eine zu geringe Flüssigkeit der Schlacke, so daß man es für nötig befand, die Schlacke durch Zusatz von Kalk, Flußspat dünnflüssiger zu machen, um das reduzierte Metall vollständig regulinisch zu gewinnen. Dabei hat man jedoch offenbar übersehen, daß letztere erschwerende Hilfsmaßnahme in dem Einzelfalle der aluminothermischen Reduktion von Berylliumoxyd unter Zusatz von Superoxyden nicht erforderlich ist, wenn man die richtige Mengenbemessung anwendet.Now the reaction mixtures from the oxides were already being used heavy fusible elements and aluminum powder chlorates, perchlorates, super oxides, Persulfates too. However, too little liquid was observed in the slag, so that it was found necessary to make the slag more fluid by adding lime and fluorspar to make in order to obtain the reduced metal completely regulinically. Has one obviously overlooks the fact that the latter aggravating remedy in the individual case the aluminothermic reduction of beryllium oxide with the addition of superoxides is not necessary if the correct quantity measurement is used.

Setzt man unter dieser Voraussetzung dem Gemisch von Berylliumoxyd mit Elementen von höherer Verbrennungswärme (z. B. Aluminium, Kalzium o. dgl.) Superoxyde zu, so kann man als Hauptreaktion die Reduktion des Berylliumoxydes zum Beryllmetall und gleichzeitig eine entsprechend hohe Wärmetönung durch die Nebenreaktion zwischen dem Superoxyde und äugesetzten Element erzielen. Dabei verläuft die ganze Umsetzung ohne weiteres völlig glatt, und gleichzeitig wird das Berylliummetall in regulinischer Form erhalten.Given this assumption, we put the mixture of beryllium oxide with elements of higher heat of combustion (e.g. aluminum, calcium or the like) super oxides to, the main reaction can be the reduction of beryllium oxide to beryl metal and at the same time a correspondingly high exothermicity due to the side reaction between Achieve the superoxide and exposed element. The whole implementation takes place without further ado completely smooth, and at the same time the beryllium metal becomes regulinic Maintain shape.

Beispiel i.Example i.

Man brennt eine Mischung von io kg Berylloxyd mit 22,4k,- Bariumsuperoxyd und mit 9,z kg Aluminium in Pulverform in einem Tiegel ab.A mixture of 10 kg of beryl oxide with 22.4k barium superoxide is burned and with 9, z kg aluminum in powder form in a crucible.

Beispiel Man bringt wie bei Beispiel i ein Gemisch von io kg Berylloxyd, 4,6 kg metallischem Kalzium, 6,o kg Aluminium und von 5,¢ kg Bariumsuperoxyd zur Reaktion.Example As in Example i, a mixture of 10 kg of beryl oxide is added, 4.6 kg of metallic calcium, 6.0 kg of aluminum and of 5. [kg] of barium peroxide Reaction.
