Precipitation of LaBO_3 on the surface of a glass of composition 0.1Cr_2O_3・25Li_2O・10La_2O_3・65B_2O_3 (in mol%) was enhanced due to ultrasonic surface treatment (UST) with aqueous and ethanol suspensions of LaBO_3 particles. The aqueous suspension gave a higher efficiency than the ethanol suspension. The crystallites were almost uniform in size distribution, and grew irregularly : increase-decrease-increase in size when heated at 580℃. Preferred growth of (200) was detected. The mechanism of UST enhanced crystallization is proposed.
