Abstract

Transparent crystallized glass with a surface crystallization layer of sub-millimeter thickness was found in the glass compositions of 35BaO-15TiO 250GeO2 (BTG50), 28BaO-18TiO254SiO2 (BTS54), and 35SrO-20TiO245SiO2 (STS45), and the precipitated fresnoite-type crystalline phase showed nonlinear optical properties. XRD measurements confirmed that BTS54 and STS45 crystallized glasses precipitate as a single phase of the fresnoite-type crystallites Ba 2TiSi2O8 and Sr2TiSi 2O8, respectively. On the other hand, BTG50 crystallized glass precipitated two phases with mainly fresnoite-type BTG, Ba 2TiGe2O8 and BaGe4O9. The results of the XRD analysis of STS45 crystallized glass demonstrated high crystal orientation in the (002) direction from the glass surface.
