In this work a manufacturing technology for a composite cathode is described. In this cathode draphite and emission-active substance forms intercalated chemical compound. These cathodes were studied in a mode of field thermo electrone emission at temperatures of 0-1100 ° C and anode voltages of 1 – 15 kV. The article contains results of determination of optimal pressing parameters, different methods of cathode surface processing and field emission current-voltage characteristics.
