Abstract
The present work is the first attempt to measure the electrical properties of compressed Egyptian natural graphite flakes obtained from the graphite schists of Wadi Sitra, Eastern Desert. X-ray diffraction patterns indicate that the graphite flakes possess high crystalline perfection. The graphite flakes were ground and compressed into pellets. The four probe dc method was used to measure the electrical resistivity as a function of temperature from 300K down to 12K. Also the transverse and longitudinal magnetoresistances were measured as a function of magnetic field up to 4.8 kG at temperatures 300K, 77K, and 12K.
