下降法生长的GdCOB晶体中的包裹物

Investigation on the Inclusions of GdCOB Crystals Grown by Bridgman Method

本文通过对GdCOB晶体进行了光学显微观察 ;结合电子探针微区分析手段 ,讨论了Bridgman法生长所得GdCOB晶体中几类不同性质的包裹物。这些包裹物主要为富钙的固相包裹物 ,组分过冷形成的熔体包裹 ,以及气泡包裹。并分析了它们的组成和成因。

Several kinds of inclusions in GdCOB crystals grown by the Bridgman method are discussed with optical microscopic observations and electron probe microanalysis.These inclusions main are the solid phase inclusions of Ca rich,the melt inclusions caused by composition supercooling and the blister inclusions.The compositions and origin of these inclusions are analyzed.
