Abstract对电阻加热引上法和感应加热引上法生长beta'-Gd_2(MoO_4)_3晶体的实验结果进行了比较,分析了两种方法生长晶体过程中熔体过冷和组分过冷的情况。研究认为组分过冷主要与生长过程中MoO_3的挥发、Gd_2(MoO_4)_3熔体的粘度及固液界面的温度梯度有关,并认为感应加热引上法较之电阻加热引上法容易得到优质晶体。

Other AbstractWe compared the experimental results of growing beta'-Gd_2(MoO_4)_3 crystal by resistance-heated and induction-heated Czochralski (Cz) technique. The constitutional supercooling and the supercooling of the melt during the Cz process were discussed. We consider that the constitutional supercooling was related to the volatilization of MoO_3, the viscosity of Gd_2(MoO_4)_3 melt and the temperature gradient in solid-liquid interface. We conclude that the high quality transparent beta'-Gd_2(MoO_4)_3 crystal grown by induction-heated Cz technique is easier than by resistance-heated Cz technique.
