Erratum to “X-ray absorption spectroscopy analysis of formation and structure of Ag nanoparticles in soda-lime silicate” by X.C. Yang, M. Dubiel, S. Brunsch and H. Hofmeister [J. Non-Cryst. Solids 328 (2003) 123–136]

Silver valence and local environments in borosilicate and calcium aluminoborate waste glasses as determined from X-ray absorption spectroscopy

“…The nearest-neighbor RDF peak for AG-CABS-4 glass is the broadest and has the smallest amplitude of all glasses investigated here, which probably indicates an average Ag-site with a range of different Ag-O distances. The RDFs for the three glasses investigated indicate no colloidal Ag in the form of Ag-metal particles, because there is no RDF peak near 2.9 Å , which correlates to Ag-Ag contributions [2,3] (Fig. 3(a)).…”

“…Silver in Ag 2 O AE nB 2 O 3 glasses [14] acts as a network modifier that is bound to oxygens within a disordered environment; average Ag-O distances in these glasses are 0.3 Å larger than those in crystalline Ag 2 O. EXAFS studies of Ag + replacing Na + in silicate and aluminosilicate glasses [15] report Ag-O distances varying from 2.08 to 2.23 Å with coordination numbers near 2.0 and large Debye-Waller factors; the Ag environments in these glasses are distinctly different from the Na environments that were replaced. Other EXAFS investigations of Ag in silicate glasses [2,3] have shown that Ag nanoparticles can coexist with network modifying Ag coordinated with oxygens. The results from these studies will be compared with our Ag XAS findings for the borosilicate and Ca-aluminoborate glasses presented below.…”

“…The solubility is highly dependent on the glass composition, temperature, and redox state. Silver incorporated in some silicate materials has been determined to be in nanometer-size Ag metal particles or colloidal Ag [2,3]. Some silver-containing glasses can be cloudy or colored, which is the result of light scattering by the colloidal Ag.…”

“…Earlier XAS work on Ag in silicate and borate glasses has generally shown that silver is coordinated by oxygens in glasses with lower Ag concentrations, while Ag clusters with itself to form silver nanoparticles in glasses with higher Ag-content [2,3,14,15]. Silver in Ag 2 O AE nB 2 O 3 glasses [14] acts as a network modifier that is bound to oxygens within a disordered environment; average Ag-O distances in these glasses are 0.3 Å larger than those in crystalline Ag 2 O. EXAFS studies of Ag + replacing Na + in silicate and aluminosilicate glasses [15] report Ag-O distances varying from 2.08 to 2.23 Å with coordination numbers near 2.0 and large Debye-Waller factors; the Ag environments in these glasses are distinctly different from the Na environments that were replaced.…”

Incorporation of silver into soda-lime silicate glass by a classical staining process

“…The experimental technique usually used to incorporate silver ions into glasses is the conventional ion exchange method, followed by appropriate subsequent treatment such as ion [2]/X-ray [3]/laser [4] irradiation or thermal treatment [5]. Staining, as an unconventional ion exchange process without using molten salts, has long been used as a method for coloring glass [6,7].…”
