- Brief description
- Open celled aluminium foam produced by infiltration of sintered salt
- Keywords
- alloy , aluminium , aluminium foam, cell , composite foam, composite material , foam , infiltration, metal, salt
- Categories
- Foam, Metal or alloy, Metal or alloy composite foam
- System
- Al
- Composition
- Not specified
- Standard codes
- Reaction
- Processing
- A precursor of sintered salt is infiltrated with molten aluminium in a press and then washed out
- Applications
- Open cell aluminium foams may be useful as surfaces for catalysts or electrochemical applications. They are also used in heat exchangers.
- Sample preparation
- Technique
- Scanning electron microscopy (SEM)
- Length bar
- 400 μm
- Further information
- This is an inexpensive route for the production of open celled foams. It allows a high degree of control over cell size and shape, and results in relatively uniform morphology. The interconnectivity of pores can be controlled by varying the degree of sintering of the precursor.
