متن کاملX-Ray Absorption Study of the Short Range Order of Tungsten and Molybdenum Ions in BaO-P2O5-WO3 and CaO-P2O5-MoO3 Glasses
The analysis of XANES and EXAFS in BaO-P20,-WO, and Ca0-P20,-MOO, glasses at the W L,,, and Mo K edges was performed in comparison with a number of crystalline WO,, CaWO,, Na,,WO,, a-MOO,, P-MOO, and amorphous a-WO,, a-MOO, compounds. The results of the EXAFS modelling by two different methods ((1) multi-shell single-scattering model within harmonic approximation and (2) model-independent radia...
متن کاملX-ray diffraction and Raman spectroscopic study of clinopyroxenes with six-coordinated Si in the Na(Mg0.5Si0.5)Si2O6-NaAlSi2O6 system
Five clinopyroxenes containing various amounts of six-coordinated Si (VISi) in the Na(Mg0.5Si0.5) Si2O6 (NaPx)-NaAlSi2O6 (jadeite) system have been synthesized at 15 GPa and 1600 °C and their structures studied with single-crystal X-ray diffraction and Raman spectroscopy. The results show that clinopyroxenes with VISi ≤ 0.33 atoms per formula unit (apfu) possess C2/c symmetry, whereas those wit...

Microstructure and Properties of Li2O-Al2O3-SiO2-P2O5 Glass-Ceramics
Serials Li2O–Al2O3–SiO2 matrix glasses and glass-ceramics with different content of P2O5 were prepared by conventional melt cooling method and crystallization process. The effects of P2O5 content on microstructure and properties such as viscosity, melting temperature and coefficient of thermal expansion (CTE) of Li2O–Al2O3–SiO2–P2O5 glasses and glass-ceramics were investigated by DSC, XRD, CTE ...
