Research abstract
TO REDUCE THE CIRCUMFERENTIAL TEMPERATURE GRADIENTS DURING THE GROWTH OF IV - V COMPOUNDS AT HIGH TEMPERATURES AND PRESSURES (1325 DEG C AND 60 ATMOSPHERES), A HEAT PIPE CONSTRUCTION IS PROPOSED. THE PREFERRED HEAT PIPE IS IN THE FORM OF A SINGLE TOROID BUILT OF A TRILAYER CONSTRUCTION OF TUNGSTEN, GRAPHITE, AND SILICON CARBIDE, AND FILLED WITH LITHIUM. MULTIPLE TOROIDAL HEAT PIPES WOULD BE STACKED BETWEEN THE CRUCIBLE AND HEATING ELEMENTS, REDUCING CIRCUMFERENTIAL GRADIENTS, WHILE ALLOWING FOR VERTICAL TEMPERATURE CONTROL. THE HEAT PIPE CONSTRUCTION WILL BE ANALYZED AND TEST STRUCTURES FABRICATED. ALTERNATIVE DESIGNS AND MATERIALS WILL BE EVALUATED.
