摘要
本文对硒酸氢铷 (RbHSeO4 ,RHSe)晶体生长过饱和溶液的均匀成核过程进行了初步的研究。通过动态目视法测量RHSe过饱和溶液的诱导期 ,讨论过饱和比、温度对诱导期的影响 ,并根据经典均匀成核理论计算不同温度下的晶体表面张力、成核自由能和临界成核半径 ,为探讨RHSe单晶的水溶液生长的较佳条件提供依据。
The process of nucleation of Rubidium Hydrogen Selenate(RbHSeO 4,RHSe) in supersaturated solution has been studied initially in this paper.The induction period of nucleation in RHSe supersaturated solution is measured by dynamics cycle observation method.The effect of supersaturation and temperature on induction period is discussed.The interfacial tension,energy of formation and critical radius of nuclei of the crystal at different temperature are calculated based on classical homogeneous nucleation theory.This provides the foundation for discussing the optimal condition of aqueous solution method of RHSe single crystal growth.
