“…Around this minimum, the energy‐volume curve was recalculated as described above, taking the structure from the initial E ‐ V curve as a starting point. The volume difference between this minimum and the jadeite (molar volume from theory V m = 62.47 cm 3 mol –1 ) amounts to 23.9 cm 3 mol –1 (38 %) and agrees well with the experimental volume difference between jadeite crystal ( V m = 60.55 cm 3 mol –1 )15 and glass with jadeite composition ( V m = 83 cm 3 mol –1 ),4 which accounts to approximately 22 cm 3 mol –1 (37 %). The theoretical overestimation of the volume is 3.1 % in case of jadeite, and the difference between the low‐density polymorph and jadeite glass is 4.1 %.…”

“…Recently, a number of glasses with compositions of the jadeite‐diopside (NaAlSi 2 O 6 ‐CaMgSi 2 O 6 ) join has been synthesized using the corresponding binary oxides as starting materials and characterized 4. It was observed that glass of the jadeite composition exhibits a significantly larger molar volume and lower bulk modulus than the jadeite crystal.…”

The high-pressure clinopyroxene mineral jadeite (chemical composition NaAlSi 2 O 6 ) was studied by density-functional theory with respect to its electronic, vibrational, and thermodynamic properties, correctly reproducing the available experimental data. At a larger-thannormal volume, however, a low-density alumosilicate phase with tetrahedral instead of octahedral Al-O coordination was identified. This low-density phase was investigated theoretically, too, and the results were compared to jadeite and experimentally observed properties of what has been dubbed jadeite glass. It turned out that the theoretically * Prof. Dr. R. Dronskowski Fax: +49 241 80 92642 E-Mail: drons@HAL9000.ac.rwth-aachen.de [a] Chair 590 obtained properties of this hypothetical polymorph, such as the bulk modulus, the molar volume and the vibrational frequencies, agree well with the corresponding properties of the glass phase. Hence, from an inverse structure-property relationship we propose to model jadeite glass with the aforementioned low-density alumosilicate phase and tetrahedral Al-O motifs, as suggested from first principles and corroborated from experiment. The possibilities as well as the limitations of electronic, phonon and thermodynamic properties calculations applied to such a polymorph are also discussed.

“…CaO-MgO-Na 2 O-Al 2 O 3 -SiO 2 (CMNAS) glasses in a diopside (CaMgSi 2 O 6 )-jadeite (NaAlSi 2 O 6 ) pseudobinary join can be regarded as an important model system for andesitic melts (e.g., Schairer and Yoder, 1960;Bell and Davis, 1969;Jindal et al, 2011;Jindal, 2012). The intermediate composition of the diopside-jadeite join can also represent high-Mg andesitic melts (defined as having Mg# P 0.45 and SiO 2 = 54-65%) (e.g., Wood and Turner, 2009).…”

The article provides a selective review on strength of glass and glass fiber, covering effects of surface flaw and surface hydrolysis on the usable strength of glass (USG). Application of Griffith-Inglis-Orowan theory on fracture of solids is demonstrated, elucidating importance of stress-assisted hydrolytic effect on glass USG and associated change in glass surface energy. The fundamental understanding of glass fracture supports critical needs for development of new glasses and new durable and/or resin compatible hydrophobic coatings to significantly improve USG of glass and fiberglass products, respectively.
