Manufacturing Routes for Metallic Foams

In a first step, about 1.5 wt.% calcium metal is added to an aluminum melt at 680 C. The melt is stirred for several minutes, during which its viscosity continuously increases by a factor of up to five because of the formation of calcium oxide (CaO), calcium-aluminum oxide (CaAl 2 O 4 ), or perhaps even Al 4 Ca intermetallics, which thicken the liquid metal.
