The results of studies high-frequency electromagnetic properties alkaline borosilicate glasses modified with lanthanum, titanium, and zirconium oxides concerning their structure are presented. values the spectral reflection transmission coefficients experimentally measured in frequency range 12–18 GHz. article presents typical spectra complex dielectric constant studied glass samples inthe 20 H...

• The solubility limit of phosphorus pentoxide in a sodium borosilicate glass was between 3 and 4 mol%. BS-SEM suggested induced nucleation-type phase separation. Phosphorus increased decreased the transition temperature. viscosity at lower temperatures. Raman spectroscopy re-polymerised network. This research has characterized effects P 2 O 5 additions on physical, chemical, thermal, rheologic...

The main goal of the present work is to unveil nature phenomena related so-called hysteresis response in electrical conductivity RuO2-glass composites melts. Therefore, a set sodium-calcium borosilicate glasses with different RuO2 contents synthesized and characterized by scanning electron microscopy coupled energy-dispersive X-ray spectroscopy. properties these are assessed impedance spectrosc...

We present a comprehensive molecular dynamics (MD) simulation study of composition-structure trends in a set of 25 glasses of widely spanning compositions from the following four systems of increasing complexity: Na2O-B2O3, Na2O-B2O3-SiO2, Na2O-CaO-SiO2-P2O5, and Na2O-CaO-B2O3-SiO2-P2O5. The simulations involved new B-O and P-O potential parameters developed within the polarizable shell-model f...
