Joining of SiC Ceramics by the Flash-Bonding Technique

Autor: Mikito Kitayama, Takuro Yoshitake, Yoshio Ohta

Publikováno v: Journal of Materials Science and Chemical Engineering. :52-65

Because Silicon carbide (SiC) ceramics have various excellent properties, the demand for larger and complicated shapes has been increasing. This paper introduces an innovative method that would not require a large furnace, and further, would minimize

Additive Manufacturing of SiC Ceramics with Complicated Shapes Using the FDM Type 3D-Printer

Autor: Hisaya Masuda, Mikito Kitayama, Yoshio Ohta

Publikováno v: Journal of Materials Science and Chemical Engineering. :1-12

Silicon carbide (SiC) ceramics have excellent properties and widely used for high temperature applications. So far, joining techniques have been applied to fabricate large SiC ceramics with complicated shapes. In this work, the additive manufacturing

Solid-State Synthesis of Metastable Ytterbium (II) Oxide

Autor: Yoshio Ohta, Mikito Kitayama, Aoi Goto

Publikováno v: Journal of Materials Science and Chemical Engineering. :85-99

Due to its electron configuration (Xe) 4 f14 6 s2, Ytterbium (Yb) could form divalent oxide, YbO. In this study, the solid-state synthesis of metastable YbO was investigated by the oxidation of Yb metal at normal pressure using two experimental condi

Phase transformation and interface segregation behavior in Si3 N4 ceramics sintered with La2 O3 -Lu2 O3 mixed additive

Autor: Yukio Sato, Ryosuke Urakami, Takeshi Nishiyama, Masayoshi Ogushi, Mikito Kitayama, Aoi Goto, Ryo Teranishi, Kazuhiro Yamada, Kenji Kaneko

Publikováno v: Journal of the American Ceramic Society. 100:1231-1240

Microstructure and mechanical property of silicon nitride (Si3N4) ceramic are strongly dependent on the selection of sintering additives. When rare-earth (RE) oxide is used as the sintering additive, segregation of RE ions at interface between Si3N4

Effects of Lanthanide Substitution on the Sintering Behavior of Bismuth Titanate Ceramics Prepared by the Chemical Coprecipitation Method

Autor: Mikito Kitayama, Kohei Nakatsuka, Yoshio Ohta

Publikováno v: Materials Science Forum. 750:328-331

Bi4-xLnxTi3O12 (Ln = La, Nd or Gd; x = 0, 0.25, 0.5, 0.75 or 1.0) fine powders were prepared by the chemical coprecipitation method. Suitable calcination temperature for each powder was determined. The effects of Ln-substitution on the sintering beha

Development of Silicon Nitride Porous Bodies with Micro-Macro Complex Pore Structure for the Application of the ‘Bio-Filter’

Autor: Mikito Kitayama, Wataru Ueta, Yoshio Ohta

Publikováno v: Materials Science Forum. 750:332-335

In order to develop the ‘Bio-filter’, Si3N4 porous bodies with micro-macro complex pore structure were fabricated. The micro-pores were successfully introduced by inserting PE meshes between the green tapes. Micro-pore size was controlled by addi
