Synthesis of La¬0.9Sr¬0.1Ga¬0.8Mg¬0.2O3-δ Powder for Solid Oxide Fuel Cell by a Nitrate-Citrate Combustion Route

Naiqing ZHANG , Kening SUN , Derui ZHOU , Ningning WU

A nitrate-citrate combustion route to synthesize La¬0.9Sr¬0.1Ga¬0.8Mg¬0.2O3-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...

Microstructure of Co-Ni-Al2O3 Composite Coatings by Electroforming

Gang WU , Ning LI , Derui ZHOU , Kurachi Mitsuo

材料科学技术（英文）

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 microstructu...

LOCAL-STRUCTURE OF THE AXIAL FE3+ CENTER IN THE K+ SITE OF A KTAO3 CRYSTAL

Physical Review B

In order to understand the unusually large value of zero-field splitting D for the axial Fe3+ center in a KTaO3 crystal, Zhou made two assumptions in his recent report [Phys. Rev. B 42, 917 (1990)]. In this Comment we will show that his assumption II is qualitatively r...

ABSORPTION-SPECTRUM AND ZERO-FIELD SPLITTING OF Y3FE5O12

Physical Review B

The assignment of the absorption spectrum of Y3Fe5O12 (YIG) made by Scott et al. [Phys. Rev. B 10, 971 (1974)] is shown to be incorrect and a new one is made by diagonalizing the complete cubic crystal-field matrices for d5 ions, involving spin-orbit interaction, given by Zho...
