| 摘 要： | 凝胶法是生长KClO4晶体最合适的方法．实验研究了反应物浓度、凝胶密度、温度、凝胶pH值对KClO4晶体成核数目、大小、形状及质量的影响，得出了生长较大尺寸、完整性好、高质量的KClO4晶体的最佳条件和参数．第一次对KClO4晶体形态、各晶面的显露程度进行定量分析，实验与理论分析相符合．证实了Hartman和Perdok的PBC理论．研究结果为下一步进行晶体生长机理研究打下了基础．

| Abstract: | Gel growth is the best method for growth of potassium perchlorate single crystals.The effect of concentration of reactants,concentration of gel,temperature,pH value of gel on crystal nucleation density,size,form and quality has been studied by experiments.The best growth parameters for growth of large size,well defined and transparent potassium perchlorate single crystals are obtained.The crystal morphology and the relative importance of crystal faces of potassium perchlorate single crystals are quantitatively analyzed for the first time,and the results are in satisfactory agreement with experimental observations.The theory of periodic bond chain(PBC) is verified in the experiment. |

| Keywords: | Gel growth potassium perchlorate single crystals the best growth parameters crystal morphology |
