Low temperature-densified NASICON-based ceramics promoted by Na2O-Nb2O5-P2O5 glass additive and spark plasma sintering

Autor: He Wang, Keisuke Okubo, George Hasegawa, Naoya Enomoto, Miki Inada, Katsuro Hayashi

Publikováno v: Solid State Ionics. 322:54-60

The effects of spark plasma sintering (SPS) and Na2O-Nb2O5-P2O5 glass additive have been examined for the sintering of Na3Zr2Si2PO12 (NASICON) ceramics. Full densification of NASICON ceramics is achieved at ~1045 °C, which is 200 °C lower than that

Publikováno v: Electrochimica Acta. 278:176-181

Ceramic sheet of Na+ ion-conducting solid electrolyte, Na3Zr2Si2PO12 (NASICON), has been prepared by tape-casting method. Addition of 60Na2O-10Nb2O5-30P2O5 glass as a sintering aid is crucial for fabrication of fully-densified impermeable sheet. Othe

Sodium ion conduction in sodium lanthanum zirconate ceramics prepared by spark plasma sintering

Autor: Kazuma Nishimi, George Hasegawa, Katsuro Hayashi, Naoto Toyomura, Naoya Enomoto, Miki Inada

Publikováno v: Scripta Materialia. 200:113887

Dense ceramics of Na3xLa2/3−xZrO3−δ with orthorhombic (Pnma) perovskite structure have been prepared by spark plasma sintering (SPS) to investigate their Na+ ion conducting behaviors combining with crystal chemistry. Despite of suppressed Na vol

Crystallization behavior of iron-based amorphous nanoparticles prepared sonochemically

Autor: Katsuro Hayashi, Shingo Hirata, Miki Inada, Naoya Enomoto

Publikováno v: Ultrasonics Sonochemistry. 35:563-568

In general, a rapid quenching is required to obtain an amorphous metal. It is known that an intensive ultrasonication generates a very high temperature within cavitation bubbles in a very short moment, which enables a rapid quenching process in a liq

Structural analysis and capacitive properties of carbon spheres prepared by hydrothermal carbonization

Autor: Katsuro Hayashi, Junichi Hojo, Miki Inada, Naoya Enomoto

Publikováno v: Advanced Powder Technology. 28:884-889

The structure and capacitive properties of carbon spheres synthesized by heat treatment after hydrothermal carbonization of glucose were investigated. X-ray diffraction, Raman spectroscopy, and 13 C NMR spectroscopy measurements revealed that the sph
