Preparation

Neodymium nickelate can be prepared by dissolving neodymium(III) oxide and nickel(II) oxide in nitric acid, followed by heating the mixture in an oxygen atmosphere.[2]

Physical Properties

Neodymium nickelate shows metal-insulator transition (MIT) under low temperature.[3][4] The temperature at which it transforms (TMIT) is 400K,[5] which is higher than praseodymium nickelate (200K) but lower than samarium nickelate (460K).[3][5][6] It transforms from antiferromagnetism to paramagnetism. It has demonstrated to be a first-order phase transition (this applies for praseodymium nickelate as well).[3] The temeperature (TN) can be changed by varying the NiO6 octahedral distortion.[3][4] It is the only lathanide nickelate to have the same TMIT as TN.[3]

Uses

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 "overstoichimoetry" of oxygen in the neodymium nickelate, making it a successful conductor of both ions and electrons.[7]

Neodymium nickelate can also be used in electrocatalysts, synapse transistors, photovoltaics, memory resistors, biosensors, and electric-field sensors.[3]
