Abstract

Nanocrystalline singlephase neodymium monoaluminate NdAlO3 has been prepared from neodymium oxide and aluminium nitrate by modified Pechini’s method Malic acid has been used for the first time as a new complexing agent in the sol–gel process It has facilitated without adding 12ethanediol a lowtemperature synthesis at 1050 °C compared to the temperature of 1630 °C needed for the solidstate preparation The characterisation of the nanoparticles has been carried out by Xray diffraction scanning electron microscopy transmission electron microscopy Xray photoelectron spectroscopy and infrared spectroscopy in the range 75–4000 cm−1 The smallest particles have size of 30 nm and are anisometric agglomerates of particles have been also observed The material has pyknometric density of 3956 g/cm3 at T = 29315 K and specific surface area 52 m2/g The binding energies of O 1s Al 2p Nd 3d and Nd 4d electrons have been found chemically shifted in NdAlO3 compared to the values for the respective elements
