N2 - Transparent glass ceramics with highly oriented surface crystalline layers of fresnoite Ba2TiSi2O8 were prepared by heat treatment of precursor glasses in BaO-TiO2-SiO2 system. The orientation along c-axis of fresnoite crystals normal to the glass surface was evaluated by the surface XRD patterns, and it was remarkably enhanced by ultrasonic surface treatment (UST) before the crystallization using fresnoite powder suspension in water. The effect of UST disappeared after heat treatment in the glass transition region, and the mechanism of UST was discussed on the basis of the persistence at elevated temperatures.
