In the present work, mixed crystals of KADP (85:15) have been grown at 45 ºC using solution growth. The growth parameters such as solubility, metastable zone width and induction period are determined experimentally. Nucleation parameters such as critical radius, interfacial tension and critical free energy of the mixed crystals are calculated. The UV-Visible spectrum shows that the mixed crystal has good optical transmission in the entire visible and near IR region. The dielectric measurements are used to analyse dielectric constant and dielectric loss of the mixed crystal. The nonlinear optical property of the grown crystal has been confirmed by the Kurtz powder technique and second harmonic generation efficiency is found to be 1.5 times that of potassium dihydrogen phosphate (KDP) crystal. Photoconductivity study shows the positive photo conducting nature of the crystal. Higher piezoelectric coefficient has been observed in mixed crystals..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
