Characterisation and compressive properties of highly porous palladium materials fabricated by spark plasma sintering with silicon as spacer

Abstract

In the present study, highly porous bulk Pd has been prepared by spark plasma sintering using silicon as a spacer material. The effects of the Si contents and sintering temperatures on the resultant porous materials were studied. It has been found that the porosity of porous Pd can be controlled by varying the content of Si, and their maximum porosity values reached 90%. The sintering temperature of 550uC and holding time of 5 min would be used to sinter porous bulk Pd with well developed necks. Meanwhile, the compressive properties of porous bulk Pd were also investigated.

“…Mechanical properties for porous Pd materials are very important for their engineering application where service gas or liquid flow is concerned [38]. Compression stress-strain curves of BHPPd materials are shown in Figure 8.…”
