HYDROGEN-GENERATING MATERIAL AND PROCESS FOR PRODUCING HYDROGEN-GENERATING MATERIAL

摘要

A process for producing a hydrogen-generating material comprising at least one metal powder selected from the group consisting of an aluminum powder and an aluminum alloy powder, characterized by mechanically pulverizing aluminum or an aluminum alloy in a treating solvent comprising an organic solvent having the property of corroding aluminum to thereby form a metal powder composed of flaky particles. The hydrogen-generating material comprises, for example, at least one metal powder selected from the group consisting of an aluminum powder and an aluminum alloy powder, the metal powder being composed of flaky particles and at least 60 wt.% of the aluminum contained in the metal powder being present in a metallic state. The metal powder has a carbon content, as determined by the infrared absorption method after combustion, of 0.5 wt.% or lower.
