Abstract :

Thermal, Mechanical and dielectrical characterizations of slow evaporation grown single crystals of Urea-Phthalic acid (UPA) are analyzed in this article. Thermal study is carried out by analysing TGA – DSC spectrum of grown samples. The melting point of the sample material is found to be 192.57 ⁰C. Mechanical properties such as Vicker’s microhardness number, work hardening index, Yield strength, stiffness constant, brittleness index, standard hardness and fracture toughness values are determined using Vicker’s microhardness tester. The dielectric study is carried out by determining dielectric constant, dielectric loss and ac conductivity and analysing the variation of these parameters with frequency and temperature.
