Glasses, and the liquids from which they are generally quenched, conspicuously lack translational periodicity and from this experimental fact it is a short step to assume that glasses are essentially disordered. In silicate glasses, the strongly covalently bonded silicon and oxygen atoms are thought to form a network structure within which ionically bonded 'network-modifying' atoms such as Li, Na, Ca, Mg and Fe substitute randomly in suitable interstices. Taken to extremes, this view leads to a… 

Insight into the structure-elastic property relationship of calcium silicate glasses: a multi-length scale approach.

It is shown for the first time the implication of the calcium framework in the elastic behavior of the glass and will contribute substantially to the understanding of the composition-structure-property relationships in multi-component industrial glasses.

Configurational constraints on glass formation in the liquid calcium aluminate system

We report new time-resolved synchrotron x-ray diffraction (SXRD) measurements to track structural transformations in calcium-aluminate (CaO)x(Al2O3)1−x liquids during glass formation, and review

Medium-range order in the cation distribution of a calcium silicate glass

Silicate glasses have conventionally been regarded as silicate frameworks in which cations are distributed at random. Neutron scattering from isotopically substituted samples allows correlations

Structural properties and medium‐range order in calcium‐metasilicate (CaSiO3) glass: A molecular dynamics study

Structural properties and medium‐range order (MRO) in calcium metasilicate (CaSiO3) glass are investigated at different concentrations of calcium oxide through the molecular dynamics technique.

Quantification of the disorder in network-modified silicate glasses

Two-dimensional 170 dynamic-angle-spinning nuclear magnetic resonance experiments reveal intermediate-range order in the distribution of inter-tetrahedral (Si–O–Si) bond angles and a high degree of Order in the disposition of oxygen atoms around the network-modifying cations.



EXAFS and XANES Spectra of Calcium Silicate Glasses

According to conventional views of the structure of oxide glasses, alkali and alkaline earth ions occupy holes of random size and variable symmetry provides by the silicon-oxygen framework. The

An EXAFS study of glassy and crystalline phases of compositions CaAl2Si2O8 (anorthite) and CaMgSi2O6 (diopside)

EXAFS spectroscopy has been used to study the local environment of calcium in glasses and crystals of anorthite (CaAl2Si2O8) and diopside (CaMgSi2O6) compositions. The glass results reveal

Non-existent silicates

Many topologically possible silicate structures do not exist, and the reasons for this are considered. Limitations on the chemical compositions of anhydrous binary silicates are discussed and

Local structure of silicate glasses

Extended X-ray absorption fine structure is used to study local order in silicate glasses around sodium and silicon atoms. It is demonstrated that modifying cations like sodium have well-defined

Structural properties of ionic liquids

Abstract Two types of ionic liquids are considered: molten salts and aqueous solutions of strong electrolytes. It is shown that in both cases, modern theoretical methods are capable of making


Huggins's empirical formula giving the volume Vo per atom of oxygen is discussed in terms of structural concepts.
