Magnetic Properties and Activity of Pt-Er/γ-Al2O3 Catalysts Lu Weiqi1,Zhang Xinquan2,Li Jianyong1,Li,Fengyi1 (1.Institute of Applied Chemistry, Nanchang University, Nanchang 330047, China;2.Jiangxi... desorption. The magnetic behavior of Pt-Er-γ-Al2O3 catalysts were studied with a Faraday magnetic balance and the results show that the addition of Er can affect the surface properties, the catalytic......
Effect of Magnetic Suspension Force in Electromagnetic Stirring on Microstructure of Al-Si Alloy () 摘要:Based on Maxwell equations, the Lorentz force in Al-Si alloy melt was calculated during the process of electromagnetic stirring using analytic approximation method. The effects of magnetic suspension force on the microstructure of Al-Si alloy were given under different electromagnetic......
