Solubility and metastable zone width for the re-crystallized salt of β-alanine was determined. Induction period measurement for the selected supersaturation ratios at room temperature (31 °C) was carried out for supersaturated aqueous solutions of β-alanine and it is noticed that induction period decreases with increase of supersaturation ratio. The nucleation parameters such as Gibbs free energy change, radius and number of molecules of the critical nucleus, interfacial tension and the nucleation rate have been evaluated by classical nucleation theory. Single crystals of β-alanine were grown using the optimized nucleation parameters by solution method and grown crystals have been subjected to various studies like XRD studies, FTIR, optical, thermal and SHG studies.
测定了β-丙氨酸重结晶盐的溶解度和亚稳区宽度。在室温（31°C）下，对选定的过饱和度比进行了诱导期测量，结果表明，诱导期随过饱和度比的增加而减小。通过经典成核理论，评估了成核参数，如吉布斯自由能变化、临界核的半径和分子数、界面张力和成核速率。通过溶液法使用优化的成核参数生长β-丙氨酸单晶，并对生长晶体进行了 XRD 研究、FTIR、光学、热和 SHG 研究等各种研究。
