AbstractWe describe here the design, main parameters, and characteristics of a forevacuum-pressure plasma-cathode electron source based on a hollow-cathode discharge. The source generates a continuous focused electron beam with energy up to 30 keV and current up to 300 mA at a pressure of 10–50 Pa. The focused electron beam reaches a maximum power density of 106 W/cm2. The source utility has been demonstrated by its application for processing and cutting of ceramic.

Sintering Conditions

The work demonstrated the sintering of zirconium dioxide ceramics by means of an electron beam produced by a plasma-cathode e-beam source operating at fore-vacuum pressure. The sintered ceramics consist of tetragonal-modified zirconium dioxide with grain size from 0.7 to 10 micrometers, depending on the sintering conditions. At constant sintering temperature, the density of the material and its grain size depend on the integrated energy injected into the sintered material by the electron beam.
