內容簡介Graphite is a soft, black crystalline form of naturally occurring carbon. In India it is abundantly available and there are three major sources namely Palamau of Jharkhand, Bolangir of Orissa and Sivaganga of Tamil Nadu. Refractory industry is the major consumer of graphite and in India Palamau and Tamil Nadu sources are used as additive for refractory industry. In this paper an attempt has been made to investigate the physico-chemical properties ofTamilnadu graphite and also behaviour of the graphite in oxidising atmosphere was investigated. Oxidation behaviour was studied in DTA/TGA by oxidising two size fractions of the graphite in controlled atmosphere to understand the effect of size on oxidation and it was found that the behaviour is independent of the size fractions considered for investigation.
