Thermal decomposition of hydroxycarbonate Cu-Fe-Cr spinel precursors
Decomposition of mixed Cu-Fe-Cr hydroxycarbonates was investigated by thermal analysis and in situ XRD and FTIR. TGA and DTA showed that increased preheating temperature removes modifying anions and decreases the spinel crystallization temperature. A disordered oxide phase containing carbonate is in...

| Zusammenfassung: | Decomposition of mixed Cu-Fe-Cr hydroxycarbonates was investigated by thermal analysis and in situ XRD and FTIR. TGA and DTA showed that increased preheating temperature removes modifying anions and decreases the spinel crystallization temperature. A disordered oxide phase containing carbonate is initially formed. The carbonate contents and crystallization temperature decreases depend on the Fe |
