Silver Foam Description
Silver foam, which contains the foamed pores, exhibits a porosity up to 85% and a pore size of up to 10 mm, which is greater than that of conventionally sintered porous metal. Metal foam is a two-phase composite material, consisting of a continuous metal matrix scaffold and a dispersed phase of pores. Consequently, its properties depend on the type of metal matrix used, the porosity and the pore structure, and are affected by the manufacturing process.
In general, the mechanical properties of foamed metal decrease with increasing porosity, while the electrical and thermal conductivities decline exponentially. When the metal foam is subjected to compression, the force distribution area increases as a result of pore collapse and the densification of the material.
Foamed silver is lightweight, exhibits significant bactericidal activity and can be utilised in the manufacture of showers, washing machines and medical dressings.

Applications of Silver Foam
* Installed in the shower:
It can protect human skin from various bacteria, including those that cause eczema, skin allergies and skin diseases, thereby maintaining scalp health and soft hair over an extended period;
* Installed on the washing machine:
Silver ions can be applied to clothing to neutralise bacteria and mould;
* Installed on the washbasin:
It can be used to disinfect fruit, vegetables, crockery, chopping boards and kitchen towels, and demonstrates marked sterilisation efficacy.
* Silver foam dressing:
For burns or the treatment of diabetic wounds, silver foam dressings demonstrate quantifiable bactericidal effects.
