This work aims to detect the percolation threshold value by two methods: a) The first method can be detected from the relation between electrical resistivity and the concentration of graphite. b)The second method is by the Laser Induced Plasma Spectroscopy. The importance of the graphite percolation threshold detection is the precise knowledge of the value at which NR transfers from a good isolator to antistatic material
