A technology for producing porous oxide ceramics by irradiating the crucible with an electron beam with an electron energy of 1.4 MeV and a power density of 2.8–55 kW/cm2 is described. The effect of the rate of the powder charge irradiation on the efficiency of the radiation synthesis—conversion of a mixture of the precursor powders into a ceramic material—is studied. It is found out that increasing the speed of the crucible irradiation with the electron beam from 0.125 to 2.5 cm/s, given an equal absorbed radiation dose, leads to an increase in the efficiency from 70 to 98%. The role of electron beam energy losses in the powder volume as a result of irradiation is discussed.
