Preparation and characterization of La0.9Sr0.1Ga0.8Mg0.2O3-δ by glycine-nitrate combustion method
Journal Title: Science Paper Online - Year 2008, Vol 3, Issue 4
Abstract
The intermediate-temperature electrolyte with perovskite-type La0.9Sr0.1Ga0.8Mg0.2O3-δ(LSGM) was synthesized using glycine-nitrate combustion and solid state reaction respectively. XRD, DC four-probe and SEM were applied to analyze the crystal structure, ionic conductivity and microstructure. The research results show that the single phase of the LSGM synthesized by glycine-nitrate combustion method can be obtained at a sintering temperature of 1400℃ for 2 h, which is obviously lower than that of LSGM prepared by solid state reaction method. A fine microstructure in the product was detected by SEM. Its conductivity reached 0.1 S•cm-1 at 850℃, which is higher than that of the LSGM prepared by solid state reaction method. It can be concluded that the glycine-nitrate combustion method is favorable in lowering the sintering temperature, enhancing the purity and improving the electrical property of the LSGM

仅采用Fr(φ)项的中长基线解算法的研究
仅采用Fr(φ)项的基线向量解算法由于不进行周跳的探测和修复，以及整周模糊度的确定等工作，无法利用双频观测值来消除电离层延迟，因而只能用于短基线向量的解算。利用IGS提供的全球电离层格网图GIM来进行电离层延迟改正，取得了较好的效...
