Abstract Scope |
During direct oxide reduction (DOR) of metal oxides with Ca in CaCl2, salt-soluble CaO is generated. Real-time measurement of the CaO concentration can, thus, be an effective way to measure reaction kinetics and determine the progress of the DOR process. Previously, Zhang et. al. reported that cyclic voltammetry (CV) with tungsten electrodes can accurately measure the CaO concentration up to 0.1 wt% in molten CaCl2. As a first step to testing this measurement method during DOR operation, the CV response was verified up to 10 wt% CaO. Results of CV in the molten CaCl2 will also be reported during reduction of CeO2 with Ca metal. |
