ANODE FOR CHEMICAL CURRENT SUPPLY AND ITS MANUFACTURING PROCESS Russian patent published in 2005 - IPC

FIELD: electrical engineering; magnesium based anodes for metal-air or water-activated chemical current supplies.

SUBSTANCE: novelty is that anode for chemical current supply incorporating magnesium and mercury has in addition gallium, proportion of ingredients being as follows, mass percent: mercury, 1.2 to 1.8; gallium, 0.3 to 0.8; total amount of metal admixtures, maximum 0.61; magnesium, the rest. Mentioned amount of metal admixtures includes (maximum), %: Fe, 0.05; Ni, 0.01; Si, 0.1; Al, 0.1; Mn, 0.1; Zn, 0.1; Cu, 0.05; Ce, 0.1. Anode manufacturing process includes anode alloy ingot production by mixing up and smelting source alloy components, aging, mixing, and crystallization of alloy, ingot rolling to produce sheets, and anode cutting to desired size, molten alloy being mixed up at final manufacturing stage under effect of electromagnetic field; then desired rate of alloy crystallization lengthwise of ingot is ensured.

EFFECT: improved heterogeneity of composition and deformability, enhanced activity of anode.
