| Abstract Scope |
Reactivity analysis has crucial importance for optimal electrolysis operation and is today monitored closely. Hydro Aluminium has been reviewing analysis with a thermogravimetric type analysis (TGA) system. The TGA instrument has continuous logging of mass loss to better than 0.01 wt%/min sensitivity and has close PID-regulated temperature control with a thermocouple sensor placed inside the test piece.
This system has been in use to determine traditional reactivity properties, like total burn-off and collected dusting. Now the system is being tested with several temperature setpoints and TGA profile analysis.
This versatile and sensitive TGA methodology is suited to investigate current anode reactivity trends like air reactivity burnoff increase year on year with changing raw materials and decreasing carboxy burnoff and dusting due to improved anode production. |
