for 8 hours to achieve homogenization. The solutions were then transferred into
the crystallization vessels having selected seed crystals and placed in a water
bath with temperature controlling accuracy of ± 0.1 0 C. Glass beakers of 250 ml
were selected as crtstallizers. The solution containing crystallizer was kept at 35
0 C for crystal growth under controlled evaporation. The crystallizer was covered
with clean lead and the controlled evaporation was allowed. Figure ( 2.11) shows
the photograph of water bath with temperature controller used for crystal growth.

Figures 2.12 (a-d), show the photographs of pure KDP, 0.3 wt % L- histidine
doped KDP, 0.3 wt % L-threonine doped KDP and 0.3 wt %, DL- methionine
doped KDP crystals, respectively.
