| Abstract: |
Abstract The electrical properties (resistance, dielectric constant and pyroelectric current) as a function of temperature in the range 30 C< T< 120 C of anthranilic acid single crystals (o- aminobenzoic add, C 6 H 4 NH 2 COOH), were accurately measured and correlated to the structural phase change that has been observed at 81 C. The activation energies of the two phases were determined. The recorded DTA thermogram supports this phase change. In addition, the mean molar susceptibility χ M of the powdered sample was accurately ... |
