Description

Die Erfindung betrifft ein Verfahren zur Herstellung von Zinkstaub, der zur Herstellung elektrochemischer Batterien bestimmt ist, die die Anwesenheit von Quecksilber erfordern. Der Zinkstaub kann dabei beispielsweise in Form von gepreßten Elektroden vorliegen.The invention relates to a method for the production of zinc dust, which for the production of electrochemical Batteries that require the presence of mercury. The zinc dust can be in the form of pressed electrodes, for example.

Es ist bekannt, daß aus Batterien mit Elektroden aus legiertem oder nichtlegiertem Zinkstaub in
nachteiliger Weise Gas (Wasserstoff) entweicht,
wenn die Batterie keinen Strom liefert. Dies re-It is known that batteries with electrodes made of alloyed or non-alloyed zinc dust in

duziert die elektrische verfügbare Kapazität und wirft insbesondere Konstruktionsprobleme auf.reduces the available electrical capacity and in particular poses design problems.

Es ist bekannt, dieses Entweichen von Gas dadurch zu vermeiden, daß der Staub amalgamisiert wird. Die Quecksilbermengen, die bei diesem Verfahren nach dem Stande der Technik verwendet werden müssen, sind relativ bedeutend. Die Amalgamisierung selbst ist ein teurer und etwas heikler Verfahrensschritt. Zudem hat dieses Verfahren den Nachteil, daß das Quecksilber nicht homogen verteilt ist.It is known to prevent this escape of gas by amalgamizing the dust will. The amounts of mercury used in this prior art process are relatively significant. The amalgamation itself is expensive and a little tricky Process step. In addition, this method has the disadvantage that the mercury is not distributed homogeneously is.

Die vorliegende Erfindung hat die Aufgabe, die obenerwähnten Nachteile zu vermeiden.The present invention aims to obviate the disadvantages mentioned above.

Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß das gesamte Quecksilber, das in der Batterie benötigt wird, oder ein Teil davon in das geschmolzene, legierte oder unlegierte Zink eingebracht wird, die geschmolzene Legierung homogenisiert und durch Pulverisierung (Atomisierung) in Staub überführt wird.According to the invention, this object is achieved in that all the mercury that is in the battery is required, or a part of it is introduced into the molten, alloyed or unalloyed zinc the molten alloy is homogenized and pulverized (atomization) is converted into dust.

Der nach dem Verfahren der vorliegenden Erfindung erhaltene Staub zeichnet sich dadurch aus, daß das im Staub enthaltene Quecksilber eine homogene Legierung mit dem Zink bildet. Es ist also in je-The dust obtained by the method of the present invention is characterized in that the mercury contained in the dust forms a homogeneous alloy with the zinc. So it is in every
