A brief introduction to the structural density of nickel foam

Foam nickel structure density yes material science field middle describe Foam nickel internal pores distributed and right overall volume Influence Quantify index , it comprehensive consider Got it Metal matrix inherent density and Foam structure introduce void volume , thereby reveal Got it This kind of Quite a few hole Material exist different application situation Down physics characteristic and performance potential .
Foam nickel have excellent of three dimensional Complete penetrate grid . proportion0.2~0.3 , yes water of1/4 , wood of1/3 , Metal aluminum of1/10 , iron of1/30 . at the same time , it have porous structure , have Broadband Sound absorption characteristic . Can cutting , bending , easy Paste , thermal conductivity powerful . all quality three dimensional three-dimensional Network structure have filter Function , gas , fluid of flow stability powerful . nickel skeleton yes hollow of , exist metallurgy state Down yes interconnected of . Porosity Gundam96-98% , accumulation density only for nickel of one fifth , specific surface product very big . still Keep Got it nickel good of physics and Chemistry able . make That become have Even widely used field of Feature new Material . For example : Chemical electricity field—— application At NiMH , nickel cadmium , The fuel cell wait , range hood wait ) , because of specific surface product big , Can reduce Energy consumption , Improve efficiency . electrochemistry project field—— electrolysis Hydrogen production , Electrocatalysis process , electrochemistry metallurgy wait .
