99.95% Pure Porous Structure Silver Metal Ag Foam For Battery Catalyst

The microstructure of silver foam has three-dimensional structure with open pores and good mechanical and processing properties. The pore size, porosity, material thickness (can be made into ultra-thin structure, about 0.1mm) and structure can be designed and manufactured according to the application requirements of users. Foam silver is made of nano or micro silver powder, and foam silver has the function of nano silver.

Silver catalysts are widely used in petroleum, chemical, pharmaceutical and other industries. Foam silver is a new functional material with high porosity, large specific surface area and good permeability. As a catalyst, it has the advantages of high activity, good stability and selectivity. It is an ideal substitute for existing silver catalysts. It is also used in the production of formaldehyde to replace the traditional electrolytic silver and pumice silver catalysts. The results show that the selectivity of foam silver catalyst is as high as 90 ~ 96%, which is 2 ~ 5% higher than the traditional electrolytic silver catalyst and 5 ~ 7% higher than the commercial pumice silver with a mass fraction of 40%. The service life can also reach more than one year.
Silver foam has super thermal conductivity. Silver is the metal with the best thermal conductivity, with a thermal conductivity of 418.6 w / (m · K). It can be used for the application of fast and efficient heat conduction and heat dissipation devices required by corresponding major equipment such as motors / electrical appliances and semiconductor electronic components.
