Magnetic Properties of Erbium Gallium Gallate under High Magnetic Field YANG Cuihong1,Cheng Haiying1,Zhang Xijuan1,Wang Wei3 (1.College of Physics Science and Technology, Yangzhou University... directions. The magnetization decreases with increasing temperature,showing good agreement with thermal effect. A strong anisotropy of the magnetization is found under high magnetic field, but when......

sites and crack growth stages in both samples. Key words: Al7075 alloy; fatigue; transient liquid phase; gallium 1 Introduction Al7075-T6 alloy has low density and high specific strength, as well...) diffusion bonding using liquid gallium interlayer was investigated. The fatigue specimen was jointed at 460 °C under 10 MPa pressure for 10 min. The TLP bonded samples were homogenized at 465 °C for 2 h......
" name="ChDivSummary">Zinc concentrate with high gallium content is one of the main resources of gallium.The gallium presents in the form of isomorphism in tetrahedron coordination with sulfur in sphalerite.The research was to investigate the amenability of zinc concentrate with high gallium to pressure oxygen leaching.The particle size,sulfuric acid concentration,oxygen partial pressure,additive......

Existing Forms of Lanthanum in Purity Steels郭锋,林勤摘 要:<正>Adding lanthanum to carbon-manganese purity steel, the existing forms of lanthanum were... of enrichment of lanthanum, the concentration of lanthanum aggregated on somewhere of grain boundary reaches as high as tens of times of its average content although the average content is very low......
temperature and an appropriate molar ratio of resin-derived carbon to silicon are favorable for producing high purity silicon carbide powders. It is found that the silicon carbide content increases slightly...,the formation of silicon carbide is based on the liquid-solid reaction,and high purity (99.8wt%) silicon carbide powders can easily be obtained. It can also be found that the optimum molar ratio of resin......
