METHOD FOR PRODUCING CATHODE MATERIAL BASED ON METAL OF PLATINUM GROUP AND BARIUM Russian patent published in 2018 - IPC C22C1/05 C22C5/04 B22F1/00 H01J1/32

Abstract RU 2646654 C2

FIELD: electricity.

SUBSTANCE: method for producing cathode material based on metal of the platinum group and barium comprises obtaining intermetallic compound of platinum group with barium by melting, its grinding in the inert-gas atmosphere or CO₂, mixing the received powder of intermetallic compound with powder of the platinum group metal, included in the mentioned intermetallic compound, in the amount necessary to obtain material with a given composition, compacting, sintering or melting in argon atmosphere. Before pressing, the obtained powder mixture is mechanically activated for 5-15 minutes.

EFFECT: method allows to increase the coefficient of secondary electron emission of alloys and, as a result, increase the yield of good devices.
