Thermomechanical properties of compositions based on polysilicates modified with boron cluster anions or SiO2 nanoparticles
Sodium liquid glass silicate compositions modified with boron cluster anions [B10Cl10]2− or [B10H10]2− or SiO2 nanoparticles have been studied. It is shown that in the silicate matrix, the presence of the polyhedral anions results in nanoscale supramolecular structures formed due to their interactio...
