Ananda Kumari 2 Department of Physics, Sree Siddaganga College of Arts, Science and Commerce, Tumkur, Karnataka, India > Research Paper 2017 6 18 2017 08 2 The high purity Analytical Reagent (AR) grade Glycine (CH2NH2COOH) and concentrated Sulphuric acid (H2SO4) were taken in the molar ratio 3:1 for the synthesis of Triglycine sulphate (TGS) respectively. The synthesized pure TGS is mixed with KDP in the molar ratio (9:1), (8:2), (7:3) and by slow evaporation technique the crystals were grown at room temperature. The Dielectric studies were performed using a LCR meter for the grown crystals. The presence of space charge polarization is confirmed by Dielectric studies. Vickers micro hardness measurement of the grown crystals reveals that hardness increases with load. The log p versus log d were plotted and work hardening co-efficient or Meyer indices (n) is determined. The functional groups are identified by Raman analysis.
