The physical principles of radiation sintering and modification of ceramic structures are considered. Sintering of corundum-zirconium ceramics in thermal and electron-beam heating methods is described. The sintering temperature of ceramics is found to be decreased (by 250 - 300°C) the case of heating by an electron beam. The modifying effect of the electron beam in ceramics sintered by the thermal method is investigated and is shown to increase its mechanical strength. The prospects of electron-beam technologies for the production of corundum-zirconium ceramics with high mechanical parameters are analyzed.
