Ruthenium tablets with a mean grain size of around 4-5 μm were prepared by vacuum hot pressing. The maximum density of 12.2 g cm(-3) was achieved with a sintering time of 2 hours. The study also showed texture and microstructure changes in ruthenium tablets with sintering time.
Ruthenium tablets with mean grain size of similar to 4-5 mu m were prepared by vacuum hot pressing (VHP), and tablets with maximum density of 12.2 g cm(-3) were obtained with sintering time of 2 h. X-ray diffraction (XRD) revealed that there was a texture change with sintering time. The microstructure of the ruthenium tablets was observed by electron backscatter diffraction (EBSD) and field emission scanning electron microscopy (FSEM). The microstructure evolution of ruthenium with sintering time is discussed.
