Generation of mid-ocean ridge basalts at pressures from 1 to 7 GPa
We propose a model for the generation of average MORBs based on phase relations in the CaO-MgO-Al2O3-SiO2-CO2 system at pressures from 3 to 7 GPa and in the CaO-MgO-Al2O3-SiO2-Na2OFeO (CMASNF) system at pressures from 0.9 to 1.5 GPa. The MELT seismic tomography (Forsyth et al., 2000) across the East Pacific Rise shows the largest amount of melt centered at 30-km depth and lesser amounts at grea...
متن کاملKinetics of Ceramic Phase Crystallization in a Glass Derived from Wastes of Iron and Steel Industry
Intensified environmental regulations have posed numerous challenges in the disposal of industrial wastes. The steel industry is one of the biggest production industries, with a considerable amount of daily wastes. Production of glass-ceramic from the steel industry waters is one of the proper solutions for this problem. In this study, the application utilization of different wastes (such as bl...

کاتالیست یک سنتز جدید برای تیواترها توصیف شده است. واکنش الکل ها با آریل، هتروآریل و آلکیل تیو ل ها درحضور 1،3،5- تری آزو- 2،4،6- تری فسفرین-2،2،4،4،6،6 هگزاکلراید ((tapc به عنوان یک کاتالیست موُثر، بازده های خوب تا عالی از تیواترها را حاصل می کند. علاوه براین، واکنش تحت شرایط بدون فلز و بدون حلال پیش می رود، بنابراین یک مکمل جالب برای روش های شناخته شده سنتز تیواترها ارائه می دهد. یک مکانیسم ا...
15 صفحه اولCrystallization kinetics of glasses
Thermophysical bases of vitrification and crystallization are discussed in terms of the enthalpy versus temperature diagram and its derivative (DTA) illustrating relaxation and glass transformation as well as crystallization of glassy and amorphous states to form stable and metastable phases. Non-isothermal kinetics are thoroughly discussed and the use of one(JMAEK) and two(SB) parameter equati...
