The development of technologies for the production of carbon black in the former Czechoslovakia is described. Emphasis is put on oil furnace black methods which were developed in a variety of countries but sometimes without success. The researchers from the Research Institute for Coke Chemistry in the former Urx Works in Ostrava managed to fulfil the task. The history of carbon black production from polyaromatic materials in Czechoslovakia documents the effect of various technological conditions on the carbon forms, which possess different properties suitable for specific technical applications.
