In glasses with the compositions (100x)(2Na 2 O•16K 2 O•8Al 2 O 3 •74SiO 2 )xBaF 2 (with x = 0 to 6), the glass transition temperature decreases with increasing BaF 2 -concentration. Samples with x = 6 were thermally treated at temperatures in the range from 500 to 600 • C for 5-160 h. This leads to

We investigated the Rayleigh scattering of ternary glass systems K O᎐MgO᎐SiO and Na O᎐B O ᎐SiO . The minimum Rayleigh scattering 2 2 2 23 2 coefficients in both glasses were considerably lower than that in pure silica glass. The Rayleigh scattering due to concentration fluctuation of Na O᎐B O ᎐SiO g
