Density has an important role in determining the variation limit of the physical properties of graphite. The density of the graphite is inversely proportional to its porosity. The porosity is produced in the structure of graphite due to the escape of volatile from the raw materials through thermal treatment during the fabrication process. There are direct and indirect methods for the measurement of porosity in the structure of graphite. Mercury and gas porosimetry are considered as direct methods, whereas the indirect method is based on bulk and picnometry density measurements. In this research work, by the use of different types of density, the pore production in the fabricated graphite has been determined.
