Neodymium nickelate is a nickelate of neodymium with a chemical formula NdNiO3. In this compound, the neodymium atom is in the +3 oxidation state.[citation needed]
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]
It can also be prepared by pyrolyzing a mixture of nickel nitrate and neodymium nitrate.[2][3]
It decomposes in high temperature (950 °C) by nitrogen:[2]
- 4 NdNiO3 → 2 Nd2NiO4 + 2 NiO + O2
It can also be reduced to the monovalent nickel compound NdNiO2 by sodium hydride at 160 °C.[4]
Physical properties
Neodymium nickelate shows metal-insulator transition (MIT) under low temperature.[5][6] The temperature at which it transforms (TMIT) is 200K,[7] which is higher than praseodymium nickelate (130K) but lower than samarium nickelate (400K).[5][7][8][page needed] It transforms from antiferromagnetism to paramagnetism. It has demonstrated to be a first-order phase transition (this applies for praseodymium nickelate as well).[5] The temperature (TN) can be changed by varying the NiO6 octahedral distortion.[5][6] It is the only lathanide nickelate to have the same TMIT as TN.[5]
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 "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.[5]
