In this study cerium silicides were used as a surrogate material to investigate the feasibility of high-energy ball milling and Spark Plasma Sintering SPS for the production of uranium silicide. Ball milling was studied as a function of time and composition. Each milled composition was then sintered by pressureless and SPS techniquesMixed silicides crystallizing in the ThSi 2 structure type of composition AE 1−x RE x Si 2 are also suitable. Other silicon sources are e.g. Si 3 N 4, perhydropolysilazane, silicon diimide, silicon or silicon carbide. Suitable dopant compounds are e.g. Eu 2 O 3 or Eu 2 Si 5 N 8, CeO 4, CeF 3, or e.g. Tris[N,N-bis(trimethylsilyl)amide]cerium.

A titanium solution was formed by first adding 3.8 g HNO 3 to 810 g water in a beaker, followed by adding 87.3 g (0.35 moles) titanium-acetyl acetone under stirring. The titanium solution was quickly added to the cerium ...


As the combined active materials, we investigated various transition metal silicides, TiSi 2, VSi 2,, CrSi 2, FeSi 2,, NiSi 2,, Cu–Si, LaSi 2,,, and MmSi 2 (Mm called cerium-rich misch metal, an alloy of light rare-earth elements). It has been demonstrated that the performance of some composite electrodes can be significantly improved by ...Synthesis was performed by ball milling in an inert atmosphere starting from commercial Mg2Si powder and Bi powder. The samples were consolidated, by spark plasma sintering, to a density >95%. The morphology, and the composition and crystal structure of samples were characterized by field-emission scanning electronic microscopy and x-ray ...

Academia.edu is a platform for academics to share research papers.The nano-structuring and heavy element substitution were also employed to greatly scatter the phonon conduction and as a result, the enhancement of power factor was observed in the diffused nanostructure of annealed ribbon samples and the enhancement was correlated to the formation of Schottky barriers at the grain boundary interface. In this study, the effect of grain boundary interfaces on ...

In this study, cerium silicides were used as a surrogate material to investigate the feasibility of high-energy ball milling and Spark Plasma Sintering (SPS) for the production of uranium silicide. Ball milling was studied as a function of time and composition. Each milled composition was then sintered by pressureless and SPS techniques.After 300-rpm ball milling speed activation, the median particle size of the sample decreased sharply to 4.416 μm, but the specific surface area increased to 4.32 m 2 /g. With the increase of ball milling speed, the median particle size and specific surface area of the sample still decreased, but the range of variation slowed down.

Ball-milling increased the activation sites on BaTiO 3 NPs, that acted as nucleating sites for β-phase due to strong O H···F C hydrogen interactions at BaTiO 3 /PVDF interfaces. The large pressure of ≈1 MPa exerted on the solution during extrusion resulted in crystallization of β-phase in PVDF.Studies show that a wide range of cerium silicides, including Ce 3 Si 2 were produced by high energy ball milling (HEBM), which is a self enclosed processing technique that can limit oxygen contami nation along with silicon and cerium loses.
