Efficiency of liquid-phase synthesis of ceramic materials under the influence of an electron beam with high penetrating power

The research conducted during of last few years showed the advantages of the method of producing of the luminescence ceramic materials as well as the other purposes ceramics with using of electron beam with high penetrating power. In this technology, an industrial accelerator generates the beam and then it enters the at- mosphere throw the hole of small diameter. The accelerating voltage of the electrons is regulated in the range of 1.4 — 2.5 MV, which, in combination with the high beam power, allows for a volumetric effect on the powder material, producing its melting in about 1 s, with virtually no contact between the melt and the walls of the crucible in which the initial batch is placed. The paper proposes a method for calculating the energy ef- ficiency of a beam during the synthesis of two-component oxide ceramics. The measurements show that the beam efficiency is on average about 50 %, and in many cases exceeds 80 %, regardless of the melting tem- perature of the synthesized ceramics and the heat required to heat and melt it.
