The separation of phases in monotectic Al-In and Al-Ga-In alloys during solidification is studied. Different cooling rates result in different morphologies and dispersions of the secondary In or Ga-In phases in an Al matrix. Both uniform dispersion of In particles in an Al matrix and layered In phase along the Al grain boundaries are produced. Ga-In liquid phases are situated primarily along the Al grain boundaries. It is the co-effects of coarsening and particle pushing in addition to a monotectic reaction in solidification. The Ga-In layer along the Al grain boundaries acts as a catalyst in splitting water and provides a passageway for oxygen to oxide the Al matrix. As a result, hydrogen can be separated from water for clean energy applications.
