Sažetak
The properties of the graphite artefacts depend on the many characteristics of the coke filler (they are usually nebulously referred to as "coke structure), which in turn depend on the composition and structure of the feedstock and on the conditions of thermal treatment. Unfortunately, no single characteristic of a coke dominates the properties of the final graphite, because of inter-property interaction which take place during the processes of carbonization and calcination through to graphitization.The paper deals with the results of an investigation of the effect of feedstock type obtained from Moslavina Basin crude oil, of high-temperature treatment and of heat-soak time on the properties and structure of coke for graphite production. The influence and interaction of the following coke properties were examined with regard to the quality of the final product: density, sulphur content (puffing character), content of metallic microconstituents, thermal expansion coefficient.
