For solving the problem that the mercury element contained in the material of a magnesium alloy anode plate of a torpedo battery makes the alloy smelting technology difficult, the invention adopts the compound amalgamation technology to add the mercury element in a nontoxic mercury compound form into molten magnesium for amalgamation, thereby having the advantages of avoiding the toxic hazard in the smelting process while obtaining a product meeting the component requirements.
Mercury is used in thermometers, barometers, manometers, sphygmomanometers, float valves, mercury switches, mercury relays, fluorescent lamps and other devices, though concerns about the element's toxicity have led to mercury thermometers and sphygmomanometers being largely phased out in clinical environments in favor
