Abstract

Information on the thermal decomposition of the double complex salt (DCS) [Cr(ur)6][Co(CN)6]⋅4Н2О (ur is urea CO(NH2)2) in the temperature range of 30–1000°C has been presented. The thermolysis of the studied DCS has been carried out in an argon atmosphere at three heating rates (5, 10, 20°C/min). The obtained TG data have been processed using the ARKS TA, and then the kinetics has been evaluated by the ARKS FK program from data for 5 and 10°C/min. The proposed multi-stage formal kinetic model provided a good fit of experimental data and showed a very reasonable prediction of decomposition at a rate of 20°C/min. It was demonstrated the formation of cyanobridge structures during thermolysis. A metastable compound Co3Cr was found in the product of thermolysis at 550°C. The mixture of the final products of calcination has been comprised Co0 (α-face-centered cubic lattice (fcc), β-fcc), Cr2O3, Cr7C3, Cr23C6, Cr21.26Co1.74C6.
