Abstract


In this present work natural fractal material coral stone has studied. X-ray diffraction, dc and ac electrical characteristics are studied. From XRD data analysis it has been established that coral stone contains nano sized clusters which is supported by dc electrical measurement. The measured complex ac conductivity of coral is found to be increased with thickness of the sample. A scaling relation between ac conductivity and thickness has been also proposed here. Over all behavior of the specimen is that like a fractal system.
