摘要
本文合成一水甲酸锂原料 ,选择适宜生长条件 ,用水溶液法培育出完美一水甲酸锂单晶 (LFM)。利用全息相衬干涉显微术对 (110 )面边界层特性进行实时观测和研究。实验表明 ,在自然对流情况下 ,边界层内折射率梯度分布函数Δn(x)和浓度分布函数Cx(x)为指数形式 ;另外 ,体过饱和度与晶面过饱和度之间呈指数关系。
Lithium formate monohydrate(LFM) raw material was synthesized and the LFM single crystals were got from solution under suitable growth conditions.Holographic phase-contrast interferometric microphotography was used in-situ to study the characteristics of the boundary layers of LFM (110) face.The experiments demonstrated the distributions of the refractive index gradient and the solution concentration within the boundary layer are an exponential function of the position under free convection.The relation between interface supersaturation and bulk supersaturation is an exponential function under our experiment conditions.
