Preparation of Nickel Metal Cloth by Solution Dipping Process

Abstract:

Polyester cloth and viscose fiber cloth used as precursors were treated by solution dipping process. After drying they were reduced and sintered in hydrogen atmosphere and finally nickel metal cloth was obtained. The effects of sintering systems on the microstructure and phases of the nickel metal cloth were studied by SEM and XRD. The reaction mechanism of the reduction sintering was investigated by TG-DTA analysis. The results show that the complete, continuous and flexible nickel metal cloth can be prepared when the viscose fiber cloth used as precursor is dipped in the NiCl2 solution and then sintered at 900 oC in hydrogen atmosphere.
