Condensation Experiments of Mg-rich Crystalline and Amorphous Silicates in Vacuum
Introduction: Magnesian silicates such as for-sterite (Mg 2 SiO 4) and enstatite (MgSiO 3) are major minerals in universe including disks around young stars [e.g., 1], shells around evolved stars, in particular, oxygen rich stars [e.g., 2, 3] and so on. It is thus important to understand evaporation and condensation behaviors of magnesian silicates, which are major phase-transformation reaction...

Acknowledgements: This work was performed in part under the auspices of the U.S. Department of Energy, NNSA by the Lawrence Livermore National Laboratory under contract No. W-7405-Eng-48 and in part at the Stanford Synchrotron Radiation Laboratory, a national user facility operated by Stanford University on behalf of the U.S...
متن کاملCrystallization Kinetics Study in Al87Ni10La3 Amorphous Alloy
In this study, the crystallization behavior of melt-spun Al87Ni10La3 amorphous phase was investigated by using X-ray diffraction and non-isothermal differential thermal analysis techniques. The results demonstrated that the amorphous phase exhibited two-stage crystallization on heating, i.e., at first step the amorphous phase transforms into α-Al phase and at second step Al11La3 and Al3Ni inter...
متن کاملSteps toward interstellar silicate mineralogy V. Thermal evolution of amorphous magnesium silicates and silica
The thermally induced amorphous-to-crystalline transition has been studied for bulk sheets and micrometre-sized particles of magnesium silicate glass (MgSiO3), nanometresized amorphous magnesium silicate (MgSiO3 and Mg2SiO4 smokes) and amorphous silica particles (SiO2). Silicate glass was produced by the shock-quenching of melts. Samples of nanometre-sized smoke particles have been obtained by ...
متن کاملNon-isothermal Primary Crystallization Kinetics of the Amorphous Fe85.3B11P3Cu0.7 Alloy
In the present research, the primary crystallization kinetics of the amorphous Fe85.3B11P3Cu0.7 alloy was analyzed using non-isothermal DSC measurements. The average and local activation energies, Ea, were determined by different isokinetic and isoconversional methods. The results obtained for activation energy in this research, show that due to the complexity of the primary crystallization pro...
