Fourier Transform Infrared Spectroscopy and 31P Magic Angle Spinning Nuclear Magnetic Resonance show the dominance of the metaphosphate species along the studied composition range, while increasing SrO led to the increase of the density, glass transition and crystallization temperatures and also the chemical durability, suggesting an increase of the reticulation of the phosphate network. The microcalorimetric dissolution in acid solution shows the decrease of the heat of dissolution as the SrO amount rises. Thermodynamic interpretations point out the occurrence of two composition domains, each one corresponding probably to the predominance of particular interactions.Show less >
