N2 - Ultrafine Nd2Hf2O7 powders with the pyrochlore structure are prepared by self-propagating hightemperature synthesis (in the Pechini version). The elemental and phase composition of the powder are studied. Microstructure is studied by scanning electron microscopy. BET specific surface areas are determined. Thermal behavior is studied by TGA/DSC/DTA up to 1473 K. The sintering kinetics of as-synthesized Nd2Hf 2O7 powder at various temperatures is studied. Nd 2Hf2O7 vaporization in the range 2400-2600 K is studied by Knudsen effusion/mass spectrometry, and the thermodynamic characteristics of this compound are determined. © 2013 Pleiades Publishing, Ltd.
