Metastability of the 10-Å Phase in the System MgO–SiO2–H2O,
01-08-1992· Abstract. The so-called 10-Å phase of the MgO-SiO 2-H 2 O (MSH) system was synthesized with 100% yields from a 3: 4 MgO/SiO 2 gel at fluid pressure of 50 kb and 500 °C, but only during runs of up to 1 h and with total H 2 O contents near 50 wt. % in the sealed capsules. The water contents determined in the run products indicate a chemical composition Mg 3 Si 4
Phase Diagrams and Chemographic Diagrams
All minerals are in the system Al 2 O 3-SiO 2-H 2 O, a three component system. So, we can plot them on a triangular diagram. Question #1. Here is the diagram with the minerals plotted. Put the mineral abbreviations (above table) next to the correct dots in the diagram.
Phase equilibrium in the system: Li2O · Al2O3-SiO2,
Liquidus and solidus temperatures for almost all of the 21 preparations along the line Li 2 O · Al 2 O 3-SiO 2, from 85 to 22 per cent silica, have been determined.Three component compounds in the system are (β-spodumene (Li 2 O · Al 2 O 3 · 4SiO 2, high temperature form, melts congruently at 1423°C.) and β-eucryptite (Li 2 O · Al 2 O 3 · 2SiO 2, melts with dissociation at
DepositOnce: Dissolution-precipitation reactions in the,
The study of mineral replacement reactions can provide detailed insight into chemical processes, if experimental simulation and natural observation are combined. Among all chemical systems, the Al2O3-SiO2-H2O is one of the most intensely studied but some of our knowledge about it is still inconsistent.
Effect of Water on Olivine Metastability in Subducting,
In all these models, however, the olivine has been anhydrous, though the presence of H2O in the (Mg,Fe)2SiO4 system is well-known to enhance the rates of phase transformation. Diedrich et al. [2005] recently determined growth rates for olivine with low (300 wt ppm) water content and found that, compared with dry samples, hydrous olivine has growth rates 1.7 orders faster at 1100°C.

Metastability - Wikipedia
In chemistry and physics, metastability denotes an intermediate energetic state within a dynamical system other than the system's state of least energy.A ball resting in a hollow on a slope is a simple example of metastability. If the ball is only slightly pushed, it will settle back into its hollow, but a stronger push may start the ball rolling down the slope.
CARBONATE EQUILIBRIA
The system can neutralize added base, but can not neutralize added acid. Another way of saying the same thing is to state that the system do not contain any alkalinity. Alkalinity is an important concept in solution chemistry and relates to the acid neutralization capacity of solutions. The definition of alkalinity for the CO 2-water system is: 2

Insights into the Hydrothermal Metastability of Stishovite,
Hydrothermal experiments aiming at the crystal growth of stishovite near ambient pressure and temperature were performed in conventional autoclave systems using 1 M (molar) NaOH, 0.8 M Na2CO3, and pure water as a mineralizing agent. It was found that the hydrothermal metastability of stishovite and coesite is very different from the thermal metastability in all

Magnesium (Mg) and water - Lenntech
Magnesium is a dietary mineral for any organism but insects. It is a central atom of the chlorophyll molecule, and is therefore a requirement for plant photosynthesis. Magnesium cannot only be found in seawater, but also in rivers and rain water, causing it to naturally spread throughout the environment.
