The Sb–Sn system has been assessed in terms of thermodynamic models for the individual phases. Expressions for the Gibbs energy as a function of temperature and composition are obtained and both phase diagram and thermochemical data are calculated and found to be in good agreement with the ...
The experimental data on phase transitions temperatures in Ag-Sb-Sn system have been obtained by DTA technique during heating and cooling cycles. To verify phase equilibria in this system, a number of 19 different samples were studied in the temperature range 100-850 °C. The existence of ...
中枢神经系统(centralnervoussystem,CNS)急性损伤后,神经元连接中断往往导致严重的神经功能障碍。由于损伤的神经轴突不能再生,最终演变成永久性组织缺陷,如脊髓外伤后脊髓空洞形成。囊腔的形成合并蛋白性细胞外基质(extracellular matrix,ECM)的缺乏严重抑制...
In this article we present the results of the investigation of the ternary Sb-Sn-Ti system obtained by the application of PXRD and SEM/EDX. Three isothermal sections at 600 °C, 800 °C and 1000 °C were derived from the collected data. Additionally, the two new ternary phases Sb...

However, inconsistencies are found in the available phase diagrams, and some phase boundaries in the Sn-Sb system have not been determined. Sn-Sb alloys were prepared, equilibrated at 160°C to 300°C, and the equilibrium phases and their compositions were determined. The β-SnSb phase has a...
