研究了Pb（Ⅱ）对磷酸二氢钾（KDP）晶体生长的影响。结果表明，微量Pb（II）抑制了KDP晶体（100）面的生长，没有观察到Pb（II）对KDP晶体的削峰作用。KDP单晶在微量Pb（II）存在下出现沙漏花样。当测定Pb（II）在溶液与棱柱形截面晶体或正棱柱形截面晶体之间的分布时，两种截面晶体中的Pb（II）浓度均高于溶液中的Pb（II）浓度。此外，铅（II）的浓度在棱柱形截面的晶体中高于在垂直截面的晶体中。
The effects of Pb(II) on potassium dihydrogen phosphate (KDP) single crystal have been observed. It is found that the growth of the (100) face of KDP crystal is suppressed under traces of Pb(II), and that no tapering for KDP crystal by Pb(II) is observed. The hourglass pattern in KDP single crystal appears under traces of Pb(II). When measuring the distribution of Pb(II) between solution and prism-section crystal or pyramid-section crystals, the concentration of Pb(II) in both section crystals is higher than that in solution. Moreover, the concentration of Pb(II) in prism-section crystal is higher than that in pyramid-section crystal.
