Description

DEUTSCHESGERMAN

Die Erfindung bezieht sich auf eine Magnesiumelektrode für Primärelemente.The invention relates to a magnesium electrode for primary elements.

Bei der Herstellung von Primärelementen, bei denen eine Magnesiumlegierung als Anodenwerkstoff Verwendung findet, versucht man seit langem, die Wirksamkeit des Anodenmetalls (Gewinnung einer Leistung von einer immer mehr zunehmenden Anzahl von Amperestunden je kg Legierung) zu erhöhen und die Verzögerungszeit (Verzögerung zwischen dem Zeitpunkt der Einschaltung der Primärzelle in einem Stromkreis und demjenigen, in dem die Zelle ein Betriebspotential dem Stromkreis zuführt) abzukürzen. In the manufacture of primary elements where a magnesium alloy is used as the anode material Is used, attempts have been made for a long time to improve the effectiveness of the anode metal (extraction of a Power of an ever increasing number of ampere-hours per kg alloy) and the delay time (delay between the time the primary cell is switched on in a Circuit and the one in which the cell supplies an operating potential to the circuit).

Zwar wurden erhebliche Fortschritte sowohl hinsichtlich dieser Merkmale bei Primärelementen mit Magnesiumanoden erzielt, doch ist ein noch weiterer Fortschritt erwünscht.Admittedly, significant advances have been made in primary elements with both these characteristics Magnesium anodes achieved, but still further progress is desired.

Dementsprechend ist Hauptziel der Erfindung eine verbesserte Magnesiumelektrode für Primärelemente mit hoher Anodenwirksamkeit und geringer Verzögerungswirkung. Accordingly, the main object of the invention is an improved magnesium electrode for primary elements with high anode efficiency and low delay effect.

Das Diagramm nach Fig. 1 zeigt den Einfluß der Aluminium- und Zinkmengen auf die Anodenleistung einer Magnesiumelektrodenlegierung, dasjenige nach Fig. 2 die Wirkung von Aluminium- und Zinkgehalten auf die Auslösung in solchen Legierungen.The diagram according to FIG. 1 shows the influence of the aluminum and zinc quantities on the anode performance a magnesium electrode alloy, that according to FIG. 2 shows the effect of aluminum and zinc contents on tripping in such alloys.

Gemäß der Erfindung wird ein aus einer Magnesiumlegierung bestehendes Elektrodenmetall geschaffen, das aus 1,6 bis 2,0% Aluminium, 1,0 bis 1,5% Zink, 0,1 bis 0,25% Calcium und im Restlichen aus handelsgängigem Magnesium besteht, das höchstens 0,005% Eisen, höchstens 0,002% Nickel und höchstens 0,1% Mangan enthält.According to the invention, an electrode metal made of a magnesium alloy is provided, that of 1.6 to 2.0% aluminum, 1.0 to 1.5% zinc, 0.1 to 0.25% calcium and the rest Commercially available magnesium consists of a maximum of 0.005% iron, a maximum of 0.002% nickel and a maximum of Contains 0.1% manganese.

Nach Fig. 1 nimmt allgemein mit Ansteigen des Aluminiums in Magnesiumlegierungen mit 0,5 bis 2,O:fl/o Zink die Anodenleistung zu.According to FIG. 1, as the aluminum rises in magnesium alloys with 0.5 to 2.0 : fl / o zinc, the anode power generally increases.

Nach Fig. 2 ist die Auslösezeit allgemein geringer bei niedrigem Zinkgehalt der Legierung. Die Kurve für 0,5 Gewichtsprozent Zink nähert sich der Auslösezeit Null bei einem Aluminiumgehalt von etwa 0,4 Gewichtsprozent. Jedoch hat eine aus einer solchen Legierung hergestellte Anode eine geringe Leistung, wie aus Fig. 1 hervorgeht.According to Fig. 2, the tripping time is generally lower when the zinc content of the alloy is low. The curve for 0.5 weight percent zinc, the trigger time approaches zero at an aluminum content of about 0.4 weight percent. However, an anode made of such an alloy is poor in performance, such as from Fig. 1 emerges.

Es wurde noch nicht erkannt, daß es in einer Legierung einen Bereich für den Aluminiumgehalt (in Beiordnung mit dem Zinkbereich) gibt, in dem sein Ansteigen (innerhalb Grenzen) zu einer erhöhten Anodenleistung und unerwarteterweise zu einer Verringerung in maximaler Auslösezeit führt.It has not yet been recognized that there is a range for the aluminum content (in Associated with the zinc area) there, in which its increase (within limits) to an increased Anode power and unexpectedly leads to a reduction in maximum trip time.

Diese maximale Auslösezeit und nicht die Mindestoder Durchschnitts-Auslösezeit wurde in Sekunden als Ordinate in Fig. 2 aufgetragen, weil sie einen Satz der Werte gibt, die die zuverlässigen Auslöseleistungs-Magnesiumelektrode für PrimärelementeThis maximum trigger time and not the minimum or average trigger time was in seconds plotted as the ordinate in Fig. 2 because it gives a set of the values which the reliable trip performance magnesium electrode for primary elements

Im Bereich von Aluminium-Zink-Beträgen gemäß der Erfindung wurden bevorzugte Ergebnisse erzielt, wenn die Elektrodenlegierung aus 1,8 Gewichtsprozent Aluminium, 1,3% Zink, 0,15 Gewichtsprozent Calcium und im übrigen aus handelsüblichem Magnesium mit nicht mehr als 0,005 Gewichtsprozent Eisen, 0,002 Gewichtsprozent Nickel und 0,01 Gewichtsprozent Mangan besteht.In the range of aluminum-zinc amounts according to the invention, preferred results have been achieved, when the electrode alloy consists of 1.8 percent by weight aluminum, 1.3% zinc, 0.15 percent by weight calcium and otherwise made of commercially available magnesium with no more than 0.005 percent iron by weight, 0.002 percent by weight nickel and 0.01 percent by weight manganese.

Die Aluminiummindestkonzentration ist möglichst 1,6 Gewichtsprozent, da sich bei weniger niedrige Anodenleistungen ergeben (35 % oder darunter). Andererseits führen Aluminiumkonzentrationen über 2,5 Gewichtsprozent zu hoher Verzögerungsarbeit.The minimum aluminum concentration is if possible 1.6 percent by weight, since it is less low Anode performances result (35% or less). On the other hand, aluminum concentrations carry over 2.5 weight percent too high deceleration work.
