PHOSPHATE GLASSES: FORMING, STRUCTURE and PROPERTIES

Optical and Thermal Properties of Mixed Alkali Phosphate Based Glasses

Glassy samples with a composition of 40P2O5&ndash;30V2O5&ndash;(30-x)Li2O&ndash; xK2O, 0<x<30 (mol %) were prepared by the conventional melt quenching technique in two forms of bulk and blown film. X-ray diffraction patterns corroborated the amorphous feature of the samples. Density of samples was investigated by using Archimedes principle. Based on absorption and reflection spectra, indirect a...

Structure and properties of strontium-doped phosphate-based glasses.

Owing to similarity in both ionic size and polarity, strontium (Sr2+) is known to behave in a comparable way to calcium (Ca2+), and its role in bone metabolism has been well documented as both anti-resorptive and bone forming. In this study, novel quaternary strontium-doped phosphate-based glasses, containing 1, 3 and 5 mol% SrO, were synthesized and characterized. (31)P magic angle spinning (M...

Molecular Dynamics Simulation of the Structure and Properties of Lithium Phosphate Glasses

A new forcefield model was developed for the computer simulation of phosphate materials that have many important applications in the electronics and biomedical industries. The model provides a fundamental basis for the evaluation of phosphate glass structure and thermodynamics. Molecular dynamics simulations of a series of lithium phosphate glass compositions were performed using the forcefield...
