Aluminum Reactions with Water Vapor, Dry Oxygen, Moist Oxygen, and Moist Hydrogen between 500° and 625°C

Abstract

The rate of reaction between water vapor and aluminum is greater than that between the metal and oxygen. Mixtures of water vapor with either oxygen or hydrogen react with the metal at the same rate as does water vapor alone. Hydrogen blisters are formed in the metal in the presence of water vapor, but none is observed when water is absent. Blister formation in water vapor is not detected if the metal is first reacted with solution.
