Development of materials for open-cycle MHD. Quarterly report ending December 1982
Pacific Northwest Laboratory (PNL) is conducting an ongoing study of channel components for open cycle, coal-fired magnetohydrodynamic generators. specifically, electrodes/insulators are being developed and tested. For this study, a hot-walled test channel with eight electrodes was fabricated for testing in the WESTF test facility at Westinghouse Research and Development Laboratory, Pittsburgh, Pennsylvania. The chanel is designed to operate hot on all four walls, thereby reducing the amount of condensed slag. The compositions of four of the electrodes in the test channel were based on hafnium oxide-rare earth oxides-indium oxide. The electrical conductivity has been measured on several compositions based on hafnium oxide-rare earth oxides-indium oxides. The results show that adequate conductivity may be obtained with reduced indium oxide content as long as praseodymium oxide is used as the rare earth.
