Abstract
IMPROVEMENTS ARE NEEDED IN THE BARRIER INDEX OF ELECTRON EMISSION FROM THERMIONIC EMITTERS AT OPERATING TEMPERATURES ABOVE 1400OC. DIRECTIONALLY SOLIDIFIED (SINGLE CRYSTAL) METAL OXIDE COMPOSITES PROVIDE A UNIQUE OPPORTUNITY TO FORM HIGH-PACKING DENSITY ARRAYS OF SMALL METAL FIBERS (1 X 106 PINS/CM2) WITH RADII OF <0.2 UM) THAT ARE SUITABLE FOR APPLICATION AS THERMIONIC EMITTERS IN ENERGY CONVERSION DEVICES. TECHNOLOGY FOR ENERGY CORPORATION (TEC) PROPOSES DETAILED ANALYTICAL AND EXPERIMENTAL INVESTIGATIONS OF THE USE OF VARIOUS SUCH METAL OXIDES WITH METAL CARBIDE MATRICESAS THE CATHODE MATERIAL IN THERMIONIC DEVICES. EXPERIMENTALDETERMINATION OF THE RELATIVE EFFICIENCIES OF THE METAL-PIN/MATRIX SYSTEMS COMPARED TO PLANAR EMITTERS WILL BECONDUCTED.
