The article presents the results of electron beam sintering of composite ceramics based on Al 2 O 3 and ZrO 2 powders. Samples were made with different contents of Al 2 O 3 and ZrO 2 components and different pressing pressures. Sintering was carried out in vacuum at a helium pressure of 30 Pa. An electron beam generated by a forevacuum plasma electron source was used for sintering. It is shown that the sintering result depends on the pressing pressure and the percentage of components. The influence of the geometry of the samples and their composition on the temperature drop over their volume during sintering has been determined.
