PROCESS OF CARBONIZATION OF CATHODE OF ELECTRONIC DEVICE Russian patent published in 1998 - IPC

FIELD: electronics, manufacture of carbonized thoriated cathodes. SUBSTANCE: proposed process of carbonization of cathodes includes degassing of cathodes in hydrogen, carbonization of cathodes in mixture of hydrogen with hydrocarbon, calcination of cathodes in hydrogen.. Carbonization of cathode is carried out in open space where regions containing hydrogen, mixture of hydrogen with hydrocarbon and hydrogen again are created. Cathodes are moved sequentially through these regions. EFFECT: enhanced functional characteristics of process, improved quality of cathodes. 1 dwg
