| 2 | Synthesis of La_(0.9)Sr_(0.1)Ga_(0.8)Mg_(0.2)O_(3-δ) Powder for Solid Oxide Fuel Cell by a Nitrate-Citrate Combustion Route显示文摘A nitrate-citrate combustion route to synthesize La0.9Sr0.1 Ga0.8 Mg0.2O3-δ powder for solid oxide fuel cell application was presented. This route is based on the gelling of nitrate solutions by the addition of citric acid and ammonium hydroxide, followed by an intense combustion process due to an exothermic redox reaction between nitrate and citrate ions. The optimum technical parameters are that the pH value is 5, and the molar ratio of citric acid to the total metallic ion is 1.5:1. X-ray diffraction characterization of calcined gel shows that pure phase was synthesized after calcination at 1400℃ for 10 h, and the TEM result shows the calcined powder with average particle size is about 150 nm. The grain resistance contributes to the total resistance of sintered pellet below 500℃. The conductivity of the sintered pellent at 800℃ was 0.07 S-1.cm-1 higher than the conductivity of YSZ(0.05S-1.cm-1 at 800℃) | Naiqing ZHANG, Kening SUN, Derui ZHOU and Ningning WUHarbin Institute of Technology, Harbin 150001, China | 2004 | Journal of Materials Science & Technology2004，20，6： | 2 |

| 6 | The Influence of Transmutation Conditions on the Adulteration Performance of Nano-scale Nickel Hydroxide显示文摘Spherical Nano-scale nickel hydroxide was prepared through precipitation transmutation method by controlling the transmutation conditions in this paper. The measurement results of XRD and TEM indicate that the crystallization of the nano-scale nickel hydroxide isβ-style and its shape is spherical with a diameter of 40~70 nanometer. The adulteration experiment shows that the adulteration ratio of nano- scale Ni(OH) 2 in common spherical micrometer-scale Ni(OH) 2 exists a optimal value (1∶9). And at this point, the utilization ratio of Ni(OH) 2 in electrodes can be raised by 10%, and the nano-scale nickel hydroxide with sphericity shape shows a better adulteration performance than that with needle shape. | 赵力 ZHANG Cuifen Zhou Derui | 2002 | High Technology Letters2002，8，1： | 1 |

| 15 | Electrochemical and microstructural characterization of cyclic redox behaviour of SOFC anodes显示文摘The oxidation of Ni to NiO in solid oxide fuel cell (SOFC) anode will result in large bulk volume change, which may change the interfaces of the two phases in the anode cermet and thus may cause significant performance degradation. The reduction and oxidation (redox) of the Ni/YSZ cermet were studied at 800 ℃. Anodic polarization measurements were performed before and after redox cycles. The anode current density at an overpotential of 100 mV kept decreasing during the whole redox treatment. It decreased from 19.11 to 7.95 mA·cm-2 after two redox cycles. Anode supported unit cell was assembled for cell′s discharge measurements. Cell performance declined after each redox cycle. The maximum power density decreased from 126.28 to 40.32 mW·cm-2. The microstructural changes after redox cycling were recorded using scanning electron microscopy (SEM). The results reveal that after re-oxidation, the Ni gets coarse and has a higher porosity; the nickel network structure turns to be desultory. | KONG Jiangrong SUN Kening ZHOU Derui ZHANG Naiqing QIAO Jinshuo | 2006 | Rare Metals2006，25，z1： | 1 |

| 17 | Microstructure of Co-Ni-Al2O3 Composite Coatings by Electroforming显示文摘The metal matrix composite coatings of Co-Ni-Al2O3 were studied by electrolytic codeposition of Co-Ni alloys and Al2O3 on a Cu substrate from a sulfamate electrolyte containing Al2O3 particles. It was illustrated from the examined results of SEM, AFM and XRD that surface morphology and microstructure of Co-Ni-Al2O3 coatings appear to be mainly influenced by variations in Co content. The high Co content coatings with hcp lattice structure have a more uniform and fine structure than that of low Co content coatings with fcc lattice structure. The codeposition of Al2O3 particles in Co-Ni alloys can not change the phase structure of solid solution, only affects the growth and orientation of crystal planes and mostly increase the d value of lattice. | Gang WU Ning LI Derui ZHOU Kurachi Mitsuo | 2003 | Journal of Materials Science & Technology2003，19，z1： | 0 |
| 18 | Electrochemical properties of La_(0.8)Sr_(0.2)FeO_(3-δ) based composite cathode for intermediate temperature SOFC显示文摘La0.8Sr0.2FeO3-δ is a new kind of cathode material for intermediate SOFC, but its electrochemical activity is relative poor for the lanthanum gallate based solid oxide fuel cell. In this paper, a novel composite cathode of La0.8Sr0.2FeO3-δ/La0.9Sr0.1Ga0.8Mg0.2O3-δ was prepared on the LSGM electrolyte substrate by screen-printing method. The results of cathodic polarization measurements show that the overpotential decreases significantly when the composite cathode is used instead of the La0.8Sr0.2FeO3-δ single layer cathode. The cathodic overpotential of the composite La0.8Sr0.2FeO3-δ/La0.9Sr0.1Ga0.8Mg0.2O3-δ cathode is 150 mV at the current density of 0.2 A·cm-2 at 800 ℃, while the cathodic overpotential of the La0.8Sr0.2FeO3-δ single layer cathode is higher than 260 mV at the same condition. The electrochemical impedance spectroscopy was employed to investigate the polarization resistance of the cathode. The polarization resistance of the composite cathode is 1.20 Ω·cm2 in open circuit condition, while the value of the single La0.8Sr0.2FeO3-δ cathode is 1.235 Ω·cm2. | ZHANG Naiqing SUN Kening JIA Dechang ZHOU Derui | 2006 | Rare Metals2006，25，z1： | 0 |
| 19 | THE INITIAL CORROSION MECHANISM OFα-PHASE ALUMINIUM BRONZE IN NaCI SOLUTION显示文摘The polarization curves of theα-PHASE aluminium bronze measured in 5%NaCl electrochemically show that the corrosion process of the alloy is controlled by the diffusion of oxygen.The corrosion surface of theα-PHASE A1 bronze in NaCl solution for a short time was analysed by X-ray Photoelectron Spectroscopy(XPS).The results indicate that the initial corrosion product of the A1 bronze consists of a simple Cu20 phase.A1 and Ni are incorporated in Cu20 lattice structure in the form of ions,and none of the aluminium compound can be detected.The authors propose that the initial corrosion mechanism ofα-PHASE A1 bronzes in NaCl solution should include oxidation,reduction and diffusion. | Zhu Xiaolong Li Renshun Wu Rengeng Zhou Derui | 1992 | Transactions of Nonferrous Metals Society of China1992，2，1： | 0 |
| 20 | Two Hypotheses of “Melanization” on Electrogalvanized Steel Surface显示文摘Melanization is harmful to the lightness of galvanized steel surface and also reduces the bonding force between a paint coat and the steel sheet. Experimental results showed that the hypothesis of Zn-Pb codeposition does not hold true, while the fact that PbSO4 micelles in sulfate bath settle on the coating surface support the second hypothesis. The authors come to the conclusions that (1) Any measure to eliminate PbSO4 micelles before or after passivation of the coating will prevent melanization; (2) PbSO4 micelles adsorbed on the surface of passivated film promote the growth of oxygen-deficient Zn oxide and result in the generation of melanization. | Ning LT, Derui ZHOU and Deyu LI Dept. of Applied Chemistry, Harbin Institute of Technology, Harbin 150001, China Kurachi Mitsuo Kyoto University, Kyoto 606-8283, Japan E-mail: liningt@ihw.com.cn | 2001 | Journal of Materials Science & Technology2001，17，3： | 0 |
