Abstract

In this paper, production of high grade pure graphite in Bonab Research Center is reported. Firstly, we will explain the various graphite production process and the results of crystal lattice analysis such as XRD, density and chemical analysis are proposed. The density of manufactured sample is 1.86 g/cm³ which makes it suitable for many high sensitive technical applications. This is the highest grade purity that has been achieved in Iran. The process of manufacturing and the structural diagnosis of the prepared graphite is explained.
