The magnesium silicate system is an important geophysical analogue and neutron diffraction data from glasses formed in this system may also provide an initial framework for understanding the structure-dependent properties of related liquids that are important during planetary formation. Neutron diffraction data collected in situ for a single composition (38 mol% SiO2) magnesium silicate glass sample shows local changes in structure as pressure is increased from ambient conditions to 8.6 GPa at… 

Pressure induced structural transformations in amorphous MgSiO3 and CaSiO3

Development of chemical and topological structure in aluminosilicate liquids and glasses at high pressure

The results, combined with ab initio molecular dynamics and classical molecular dynamics simulations using a polarizable ion model, reveal a continuous increase in Al coordination by oxygen, with 5-fold coordinated Al dominating at 15 GPa and a preponderance of 6-foldcoordinated Al at higher pressures.

Elastic properties and structures of pyrope glass under high pressures

Abstract X‑ray diffraction analysis and ultrasonic measurements of a glass with the pyrope composition were conducted to determine its structural and elastic properties at pressures from 1 atm to

The combined results help to show that the coordination number of network-forming structural motifs in a wide range of glassy and liquid oxide materials can be rationalised in terms of the oxygen-packing fraction over an extensive pressure and temperature range.

Pressure-induced changes in interdiffusivity and compressive stress in chemically strengthened glass.

A specially designed gas pressure chamber is employed to compress bulk glass samples isostatically up to 1 GPa at elevated temperature before or after the ion exchange treatment of a commercial sodium-magnesium aluminosilicate glass, which leads to a decreased Na(+)-K(+) interdiffusivity, increased compressive stress, and slightly increased hardness.

This topical review examines methods for high pressure synchrotron x-ray diffraction of liquids and the wide variety of systems which have been studied, from simple liquid metals and their remarkable complex behaviour at high-pressure, to molecular-polymeric liquid–liquid transitions in pnicogen and chalcogen liquids, and density-driven structural transformations in water and silicate melts.

Investigations of high pressure phase diagrams of MgO-SiO2 systems with laser shock compression

Two decades of exoplanet discoveries brought the physics of planetary interiors among the topics of broad and current interests. To advance in this field, one of the key ingredient is the knowledge

Spin and valence states of iron in Al-bearing silicate glass at high pressures studied by synchrotron Mössbauer and X-ray emission spectroscopy

Abstract High-pressure synchrotron Mössbauer (SMS) and X-ray emission (XES) spectroscopic measurements were conducted to investigate the spin and valence states of iron in (Al,Fe)-bearing magnesium



In situ diffraction studies of magnesium silicate liquids

Primitive MgO–SiO2 liquids dominate the early history of the Earth and Terrestrial planets. The structures of these liquids and structure-dependent properties, such as viscosity and diffusion, are

Coordination changes in magnesium silicate glasses

Glasses made from the magnesium silicate minerals enstatite (MgSiO3) and forsterite (Mg2SiO4) and three intermediate compositions can be considered as analogues of quenched melts from the Earth and

Feasibility of in situ neutron diffraction studies of non-crystalline silicates up to pressures of 25 GPa

There is an increasing interest in the structural modifications found in liquids and amorphous systems as a function of pressure. Neutron diffraction is a key technique for determining these

Changes in the local environment surrounding magnesium ions in fragile MgO-SiO2 liquids

X-ray diffraction data have been collected in situ for a series of magnesium silicate liquids between and including the two mineral compositions enstatite and forsterite (MgSiO3 and Mg2SiO4). The

Establishing the structure of GeS2 at high pressures and temperatures: a combined approach using x-ray and neutron diffraction

A method is described for correcting x-ray diffraction data taken in situ under high pressure, high temperature conditions for a cylindrical sample, container and gasket geometry with a parallel incident beam and with a scattered beam that is defined using an oscillating radial collimator.

Probing of bonding changes in B2O3 glasses at high pressure with inelastic X-ray scattering

Full understanding of atomic arrangement in amorphous oxides both at ambient and high pressure is an ongoing fundamental puzzle. Whereas the structures of archetypal oxide glasses such as v-B2O3 at

Structure of GeO(2) glass at pressures up to 8.6 GPa

The structure of GeO2 glass at pressures extending from ambient to 8.65 GPa was measured at 25 °C by using in situ neutron diffraction. The results show a gradual change in the intermediate range

Relationship between topological order and glass forming ability in densely packed enstatite and forsterite composition glasses

This unusual structure-property relation of Mg2SiO4 glass demonstrates that by using containerless processing it may be possible to synthesize new families of dense glasses and glass ceramics with zero porosity.

Neutron powder diffraction at pressures beyond 25 GPa

Full structural studies of condensed media under high pressure by neutron powder diffraction have been limited in practice to 2–3 GPa for several decades. This range is in general too small to allow
