Abstract:
The effects of temperature, time, and the composition of the solvent (water, HCl) on the processes of leaching of Na, Al, and Ca from sodium aluminosilicate fiberglass materials and also the physicochemical properties of the leached products were studied by inductively coupled plasma atomic emission spectroscopy, differentiating dissolution, and IR spectroscopy. It was found that, in water and aqueous HCl solutions, the process is dominated by the extraction of sodium from the glass because of the ion exchange of Na+ for H+. The Na leaching rate in H2O is limited by the ion-exchange rate on the glass fiber surface, and that in HCl is controlled by the Na diffusion in the bulk of the glass fiber. The structure of the leached glass fibers is formed by alternate sheets of several silicon–oxygen tetrahedra separated by narrow voids, which contain a considerable amount of molecular water and SiOH groups, characterized by the band of stretching vibrations of OH (ν = 3640 cm–1). In annealing, SiOH groups condense to release water; however, the ionexchange properties of the fibers are partially conserved.
