Abstract
This paper is an experimental investigation on thermo chemical characteristics of corrosion reaction of iron powder. Putting iron powder, powdered active carbon and saline solution into mini-autoclave, its inside was replaced with oxygen, and a reaction velocity was examined from the decrease in pressure. A reaction velocity depends on the temperature, the volume of saline solution, and the reaction rate of iron powder. Reaction velocity rose with temperature and saline solution in this experimental condition. However, it decreased drastically in too large volume of saline solution.
