Resumo

Nanocrystals of the neodymium nickelate (Nd₂NiO₄) compound have been synthesized using the method of the combined crystallization of nitrates’ solutions and its electrophysical properties have been investigated. It has been established that Nd₂NiO₄ is characterized with rather high specific conductivity of the metallic type (∼200 S cm^–1) in the temperature range 500–900°C and the thermal expansion coefficient comparable with that of solid solutions based on ZrO₂.
