| الملخص: | Title screen The results of experiments on the sintering of alumina ceramics by electron beam generated by plasma electron source at the forevacuum pressures are presented. Surface of the discs compacted from dry alumina or zirconia nanopowders was irradiated. The discs were compacted by the technique of powerful ultrasonic action on powder during pressing. The sintering process was carried out at pressures in the range of 10-20 Pa, the electron beam with an energy of 10 keV and a current density of 5 A/cm 2. It is shown that irradiation of the surface of the compacts is possible to obtain samples of alumina ceramics with a density of 91,4 % from single-crystal state, and density of 97,2 % for zirconium ceramics. Optimal parameters of the electron beam and exposure time were determined experimentally. The regimes allowed obtaining the alumina ceramic samples sintered by the electron beam.
