| The problems of calcining and grinding of electrode coke
made from Estonian oil shale were studied with the view to obtain conductive fillers for
preparing electrically conductive compositions. Calcining of crude coke in the temperature
range of 800-1000 °C with the following disintegration was found to yield electrically
conductive fillers with the resistivity of 1.8 · 10 -2 2.4 · 10 -2 · cm and particle size of
1-4 µm. The obtained fillers are suitable for producing antistatic conductive compositions.
