Individual‐Layer Thickness Effects on the Preferred c‐Axis‐Oriented BiFeO3 Films by Chemical Solution Deposition

01-Jun-2010 | Tang, Xianwu; Dai, Jianmin; Zhu, Xuebin; Yin, Lihua; Ang, Ran; Song, Wenhai; Yang, Zhaorong; Sun, Yuping; Zhang, Ruili, Journal of the American Ceramic Society, 2010

BiFeO3 films are prepared directly on n-type Si (100) substrates using chemical solution deposition method. The effects of individual-layer thickness via controlling the solution concentration on the texture, morphology, magnetic properties as well as the magnetoelectric properties are ...

The Concept of a Low‐Temperature Synthesis for Superparamagnetic BaFe12O19 Particles

01-Jun-2010 | Drofenik, Miha; Ban, Irena; Ferk, Gregor; Makovec, Darko; Žnidaršič, Andrej; Jagličić, ..., Journal of the American Ceramic Society, 2010

Superparamagnetic Ba-hexaferrite, BaFe12O19, nanoparticles were prepared by reacting tetrahydroxoferrates (III), [Fe(OH)4][minus](aq), and barium ions, Ba2+(aq), in an autoclave in the presence of a high concentration of hydroxide ions OH[minus]. The synthesis temperature was between 80° and ...

New Negative Temperature Coefficient Ceramics in Ca–Ce–Nb–M–O (M=Mo or W) System

01-Jun-2010 | Deepa, Mannarakoth; Rao, Padala Prabhakar; Sumi, Sreedevi; Radhakrishnan, Ambiyil Narayana Pillai; Koshy, Peter, Journal of the American Ceramic Society, 2010

A series of quaternary powellites with varying cerium contents in a Ca[ndash]Ce[ndash]Nb[ndash]M[ndash]O (where M=Mo or W) system has been synthesized through the solid-state route. Powder X-ray diffraction analysis shows that these compounds crystallize in a tetragonal powellite structure with ...

Yttrium‐Doped Barium Zirconate Powders Synthesized by the Gel‐Casting Method

01-Jun-2010 | Gao, Dongyun; Guo, Ruisong, Journal of the American Ceramic Society, 2010

BaZr0.9Y0.1O2.95 powders were synthesized using both gel-casting process and solid-state reaction. The gel-casting process with citric acid as the complexing agent could result in nanoparticles with a single perovskite phase. Lower calcining temperature and shorter holding time were required to ...

Time‐Domain Response Simulation of ZnO Varistors by Voronoi Network with an Actual Grain Boundary Model

01-Jun-2010 | Long, Wangcheng; Hu, Jun; He, Jinliang; Liu, Jun, Journal of the American Ceramic Society, 2010

A special simulation model for the time-domain responses of ZnO varistors is proposed in this paper. This model is based on the Voronoi network and contains the actual conduction mechanism of the grain boundaries, as well as the capacitances of the grain boundaries. The AC responses of the actual ...

Reactions in Eucryptite‐Based Lithium Aluminum Silicates

01-Jun-2010 | Jochum, Timothy; Reimanis, Ivar, Journal of the American Ceramic Society, 2010

The reaction sequence to synthesize [beta]-eucryptite, LiAlSiO4, from the raw ingredients SiO2, Li2CO3, and Al2O3 was studied using thermal analysis and X-ray diffraction techniques. Reactions were examined by heating the raw ingredients as two-component and three-component mixtures in air, then ...

An investigation on Structure and Electrical Conductivity of Sm0.5−xGdxSr0.5CoO3−δ

01-Jun-2010 | Zhou, Fen; Zhong, Chongying; Song, Xiwen; Hao, Xihong; An, Shengli, Journal of the American Ceramic Society, 2010

Sm0.5[minus]xGdxSr0.5CoO3[minus][delta] (SGSC, x=0, 0.1, 0.2, 0.3, 0.4, 0.5) powders were synthesized by a solution-combustion method. SGSC formed the major perovskite phase with an orthorhombic symmetry after calcined at 1200°C. The electrical measurements indicated that the Gd3+content have a ...

Bismuth Borosilicate‐Based Thick Film Passivation of Ag Grid for Large‐Area Dye‐Sensitized Solar Cells

01-Jun-2010 | Yeon, Deuk Ho; Kim, Kyung Kon; Park, Nam Gyu; Cho, Yong Soo, Journal of the American Ceramic Society, 2010

A bismuth borosilicate glass-based thick film having a low glass transition temperature of 445°C was investigated as a passivation layer for protecting Ag-grid against corrosive reactions with the common I[ndash]/I3[minus] electrolyte for large area dye-sensitized solar cells (DSSC). Glass paste ...

Design, Preparation, and Characterization of Graded YSZ/La2Zr2O7 Thermal Barrier Coatings

01-Jun-2010 | Chen, Hongfei; Liu, Yun; Gao, Yanfeng; Tao, Shunyan; Luo, Hongjie, Journal of the American Ceramic Society, 2010

Large-area spallation and crack formation during service are big problems of plasma-sprayed thermal barrier coatings (TBCs), owing to their weak bond strengths and high residual stresses. Functional gradient TBCs with a gradual compositional variation along the thickness direction are proposed to ...

Phase Characteristics and Piezoelectric Properties in the Bi0.5Na0.5TiO3–BaTiO3–K0.5Na0.5NbO3 System

01-Jun-2010 | Zhang, Shan‐Tao; Wang, Lei; Chen, Yan‐Feng; Kounga, Alain Brice, Journal of the American Ceramic Society, 2010

Lead-free 0.94Bi0.5Na0.5TiO3[ndash](0.06[minus]x)BaTiO3[ndash]xK0.5Na0.5NbO3 (x=0[ndash]0.06) ceramics were prepared. All these compositions have a structure close to the rhombohedral[ndash]tetragonal morphotropic phase boundary (MPB) and good electric properties at room temperature. No ...
