Аннотация: Nanopowders of zinc and titanium oxides were used to obtain samples of Zn2TiO4-ZnO ceramic. Phase formation as well as the microstructure and elemental composition of the phases formed were studied by means of electron microscopy. The density and porosity were calculated, and the sizes of grains and pores in the ceramic were determined. The temperature at the zinc titanate forms was determined. It was shown that it corresponds to the sintering temperature of electrocontact materials with this composition. It is proposed that zinc titanate and oxide be used as arc-suppressing and dispersion-hardening additional additives in copper-based electrocontact materials.
