り出すことは公知である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a new method for the preparation of zinc powder intended for the production of electrochemical cells, the curved lead powder being in the form of an electrode, obtained for example by compaction. . Batteries containing electrodes made of zinc powder, whether alloyed or not, allow harmful escape of gas (hydrogen) when the cell is not producing current, reducing capacity and creating structural problems. is publicly known.
このようなガスの逃げを粉末を混和する公知のブラクチ
スにより避けることは公知である。It is known to avoid such escape of gases by means of known powder blends.
しかしこの公知の方法で使用される水銀の量は比較的重
要であり混和はそれ自身費用がかかり微妙な操作を構成
する。しかしこの方法は水銀の非均質分配の欠点をもつ
。However, the amount of mercury used in this known process is relatively important and the incorporation itself constitutes an expensive and delicate operation. However, this method has the disadvantage of non-homogeneous distribution of mercury.
本発明は上記欠点を避ける。The present invention avoids the above drawbacks.

の一部又は全部が合金か否かを問わず溶融亜鉛中に導入
され、溶融合金は均質にされ粉砕により粉末中に搬送さ
れることを特徴とする。The present invention is used in a method for manufacturing zinc powder for electrochemical batteries that requires the presence of mercury, and part or all of the mercury required for batteries is introduced into molten zinc regardless of whether it is an alloy or not. The molten alloy is homogenized and conveyed into powder by grinding.
本発明の方法により得られる粉末は、亜鉛と共に均質な
合金の形を形成する粉末の中に含まれることを特徴とす
６゜結果として水銀は各大きさの粉末に金属の完全な排
出まで等しく予め定められた量で有効になるであろう。The powder obtained by the method of the invention is characterized in that, together with the zinc, it is contained in the powder forming the form of a homogeneous alloy.6° As a result, the mercury is distributed equally in each size of powder until the complete evacuation of the metal. It will be effective in a predetermined amount.
例 ９礁の溶融亜鉛が６部の水銀と混合される。example Nine parts of molten zinc are mixed with six parts of mercury.

次いで３ＸＩＯＰａの圧力・で圧縮空気で粉末化され、
そこで１００Ｎ５００，４の範囲の粒度の粉末を得る。This mixture becomes homogeneous at a temperature of about 420°C.
% water plate alloy is produced. This molten alloy is then pulverized with compressed air at a pressure of 3XIOPa,
A powder with a particle size in the range of 100N500.4 is then obtained.
このようにして作られた粉末は従来の水銀を含む亜鉛粉
末と比較すると以下の利点を有する。The powder thus produced has the following advantages compared to conventional mercury-containing zinc powder:
（１，１ガス化の割合か非常に低く、アルカリ性電解液

ロリツターのガス発生割合を示す。(The rate of 1,1 gasification is very low, meaning that only a very small amount of hydrogen escapes when it comes into contact with an alkaline electrolyte.) An electrolyte consisting of 12N potassium hydroxide saturated by a l!lI conversion vessel. In the book, a powder book showed a gas evolution of 1.5 microliters per gram per day at 45°C, whereas zinc powder containing 6% mercury was produced by contacting an aqueous mercury melt. The conventional mercury-containing zinc powder produced exhibits a gas evolution rate of 5 microliters per gram per day under the same conditions.

バッテリーの電気容量を増大する結果になる。As a result of the above two advantages, when using the powder of the invention instead of conventional powders to make batteries, it is possible to use powders with low mercury content and small particle size;
This results in an increase in the electrical capacity of the battery.
