The method of electron beam heating of a mixture of yttrium and zirconium oxides for the synthesis of complex oxides has been implemented. It is established that the applied technology of melting the mixture of oxides leads to the formation of fluorite phases. It is determined that homogenization of the initial mixture of oxides should be carried out in a high-energy mill, which will reduce the temperature and duration of the synthesis of complex oxide compounds, including the desired structure of pyrochlorine. It is proposed to improve the technique of intensive thermal influence on the process of pyrochlorine synthesis by using an equiatomic alloy Y-Ti (65 wt.% Y-35 wt% Ti), which has been smelted using the arc melting method in an argon atmosphere. It was found that hydrogen saturation reduces the efficiency of pyrochlorine synthesis and increases the grain size, which may be associated with grain growth at the stage of hydrogen saturation.
