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.
