Plasma Accelerator and Energy Conversion Research
Abstract
The tasks were: 1. To construct by magnetron sputter deposition three AMTEC porous electrodes of 1-3 micron thickness, one of LaB6 on a beta'-alumina solid electrolyte tube, and two of molybdenum-titanium alloy, one of which shall be in the range of 0.2% - 0.5% titanium and the other in the range of 0.5% - 5% titanium. 2. To characterize the morphology and composition of the deposited electrodes before and after high temperature operation and sodium electrolysis by scanning electron microscopy and ion microprobe chemical analysis. 3. To investigate the electrochemical performance and measure sodium vapor transport properties of the deposited electrodes by determining current-voltage characteristics and by current interrupt measurements. A current interrupt test circuit was to be designed and assembled for this purpose. 4. To analyze electrode performance in terms of chemical and morphological characteristics and the relation of these characteristics to electrochemical processes at the beta'- alumina interface and sodium flow characteristics.
