Effect of pH value on the scatter particles in KDP crystal

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.
