pH值对KDP晶体中散射颗粒的影响
Effect of pH value on the scatter particles in KDP crystal
-
摘要: 探讨了不同pH值对KDP晶体散射颗粒的影响。结果表明，不同pH值生长条件下生长的KDP晶体中散射颗粒的尺寸、密度呈现明显差异，pH值为5.5条件下KDP晶体中散射颗粒尺寸明显变大，分布稀疏；pH值为2.0时，散射颗粒密度高，尺寸小。其原因在于形成散射的杂质颗粒的存在形式不同。Abstract: Effect of pH value on the scatter particles in KDP crystal was discussed in this paper. The results showed that scatter particles have different size and density at different growth pH value. It can be seen from the results that the scatter particles are larger and have lower density at high pH value comparing with those at low pH value. The reason can be attributed to that at different pH value the existence of ligand of Fe is not the same, which caused the impurities formed on the moving steps are not same. It is these kinds of impurities formed by ligand of Fe caused the inclusions in KDP crystals.
