A simple eutectic type phase diagram has been established between benzil and m-nitroaniline (m-NA) system. Enthalpy of mixing, solid–liquid interfacial energy, entropy of fusion and excess thermodynamic functions were calculated based on enthalpy of fusion values, determined by the DSC method. The studies concerning the X-ray powder diffraction and the infrared spectroscopy reveal the composite nature of the eutectic and 5 mol% m-NA added benzil. The dielectric constants of eutectic, 5 mol% m-NA added benzil and parent components decrease with increase in frequency (1 kHz–10 MHz) at 27°C. The dielectric constant values of these composites lie between those of m-NA and benzil. The second harmonic generation efficiencies (measured using Kurtz's powder technique) of the hot-pressed composite samples are less than that of pure m-NA.
