[2][3] It decomposes in high temperature (950 °C) by nitrogen:[2] It can also be reduced to the monovalent nickel compound NdNiO2 by sodium hydride at 160 °C.

[4] Neodymium nickelate shows metal-insulator transition (MIT) under low temperature.

[5] In a 2010 study, it was found that neodymium nickelate as an anode material provided 1.7 times the current density of typical LSM anodes when integrated into a commercial SOEC and operated at 700 °C, and approximately 4 times the current density when operated at 800 °C.

The increased performance is postulated to be due to higher "overstoichiometry" of oxygen in the neodymium nickelate, making it a successful conductor of both ions and electrons.

[9] Neodymium nickelate can also be used in electrocatalysts, synapse transistors, photovoltaics, memory resistors, biosensors, and electric-field sensors.
