Abstract
Tailoring glasses to specific applications requires a deep understanding of the interplay between material composition and structure and how this relationship governs the properties of the final product. Although this interdependence is fundamental for all glass systems, it becomes particularly critical for amorphous materials intended for interaction with biotic environments, where an inappropriate release rate or dosage of beneficial ions from the vitreous matrix may interfere with essential biological processes. This study aims to elucidate the structural evolution of multicomponent silicate-phosphate glasses in response to sulfur addition and to clarify the role of phosphorus content in controlling the sulfate capacity of these materials, designed as ecological SO42− carriers for plants. To preliminarily characterize the fabricated SiO2-P2O5-K2O-MgO-SO3 glasses, differing in P2O5 and sulfur content, the XRD, XRF, and SEM/EDS methods were employed. It was found that the higher-phosphorus system exhibits a markedly lower sulfate capacity than its lower-phosphorus counterpart. Comprehensive spectroscopic investigations (FTIR, Raman, 29Si and 31P MAS-NMR, XAS methods) revealed that the incorporation of sulfate ions into the multicomponent silicate-phosphate glasses favours network polymerization, which involves both their subnetworks: not only the predominant silicon-oxygen network but also the phosphorus-oxygen one. The study demonstrates that the sulfate capacity of a given system is governed by the polymerization degree of the vitreous matrix, which is itself controlled by the material's phase assemblage and by the distribution of network-modifying cations among the individual structural units.
