Utjecaj temperature na izdvajanje željeza, natrija i kalcija iz čađe

The aim of this paper was to show how the heat treatment up to 2000 C influenced the carbon backs dematalization. Thermal stability is important characteristic of carbon blacks and for that reason changes in metal fraction before and after heat treatment of samples at 1200, 1600 and 2000 C, were examined. The samples were subjected 4 hours to high temperatures while heating rate was 10 C/min-1. The results showed that iron, sodium and calcium mass fraction depended on temperature, because, during heat treatment partial separation of investigated metals took place.
