本文研究了Li_2B_4O_7单晶中不透明区的产生和性质，并成功地生长出直径达55 mm，长80 mm的无不透明区的Li_2B_4O_7单晶。不透明区域包含夹杂物和Pt枝晶，并且通过将存在于熔体中的空隙并入晶体中而发生。形成空隙的杂质几乎是起始物料中所含的H2O。还研究了晶体中声表面波速度的分布。
Abstract The occurrence and nature of opaque regions in Li2B4O7 single crystal have been examined; the opaque region-free Li2B4O7 single crystal, up to 55 mm in diameter and 80 mm in length, has been successfully grown. Opaque regions contain inclusions and Pt dendrites, and have occurred by incorporation of voids, existing in the melt, into the crystal. Impurity, forming voids, is almost H2O which was contained in starting materials. The distribution of SAW velocity in the grown crystal has also investigated.
