摘要
本文报道了以Bi2 O3 和GeO2 粉末为原料 ,采用改进的Bridgman法生长的大尺寸单晶中的散射芯现象。借助于显微镜和电子探针对散射芯进行了研究 ,发现散射芯主要是由铂金微颗粒组成。分析了散射芯产生的原因 。
In this paper, the scattering inclusions which often exist in the large-size Bi 4Ge 3O 12 single crystals grown from the mixture of Bi 2O 3 and GeO 2 powders by Bridgman method are reported.It was found that they mainly consist of platinum particles by microscope and electrom microprobe. Their formation cause was analy-zed,and some elimination measures were suggested.
