Synthesis, Growth and Nucleation Kinetics of Potassium Hydrogen Oxalate Hydrate Single Crystal (C4H3KO82H2O) - A Third Order Nonlinear Material

Slow evaporation method was usedto develop the metal organic compound of potassium hydrogen oxalatehydrate. The crystal system and lattice constant of the developed compound were analyzed with the help of singlecrystal X-ray diffractiontechnique. For diverse temperature,the nucleation curve and solubility of the compound werecalculatedexperimentally. The solubility curve showed that the compound exhibit a positive temperature gradient of solubility. Various parameters for growth kinetics such asfree energy change, induction period, nucleation rate wereevaluated experimentally. The semiconductor laser of wavelength 532 nm was utilizedin the Z-scanmethod to determinedifferent nonlinear parameters likethird-order refractive index, susceptibility and absorption coefficient.
