| titleOfInvention | Process for producing tungsten-alloy emitter type electrode |
| abstract | AN EMITTER TYPE ELECTRODE COMPRISING A HEAD CONSISTING ESSENTIALLY OF A MOLDABLE EMISSIVE ELECTRODE MATERIAL, TUNGSTEN, AND FROM ABOUT 0.2% TO ABOUT 7% OF A GROUP V111 METAL ADDITIVE THAT LOWERS THE SINTERING TEMPERATURE OF TUNGSTEN AT LEAST ABOUT 100* C. AND INTEGRAL WITH SAID HEAD AND EXTENDING THEREFROM, AN ELECTRICALLY CONDUCTIVE TENGSTEN ALLOY LEAD CONSISTING ESSENTIALLY OF TENGSTEN AND FROM ABOUT 1% TO ABOUT 30% RHENIUM. IN THE PROCESS FRO PREPARING EMITTER-TYPE ELECTRODES HAVING AN INTEGRAL HEAD AND LEAD BY MOLDING, PRESSING AND SINTERING THE IMPROVEMENT COMPRISING ADDING TO THE MOLDABLE, EMISSIBE ELECTRODE MATERIAL AND TUNGSTEN, THAT FORMS THE HEAD, PRIOR TO PRESSING AND SINTERING, FROM ABOUT 0.2% TO ABOUT 7% OF A GROUP CIIIMETAL ADDITIVE AND INSERTING INTO THE HEAD PRIOR TO PRESSING AND SINTERING A TUGSTEN ALLOY LEAD CONSISTING ESSENTIALLY OF TUNGSTEN AND FROM ABOUT 1% BY WEIGHT TO ABOUT 30% OF RHENIUM. |
