A new method for calculating the specific surface area of porous metal foams

摘要

Porosity and pore diameter are two elementary parameters that are easy to be measured for porous materials. A new method is proposed for calculating the specific surface area of porous metal foams based on a mathematical relationship between this area and the porosity and pore diameter. Using this method, the specific surface areas of metal foams prepared by different methods, namely electrodeposition and high-pressure permeation casting, are successfully calculated. The results indicate that the present model can accurately describe experimental data.View full textDownload full textKeywordsporosity, porous metal, metal foam, specific surface areaRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/09500831003745571
