Abstract

The datasets presented here are related to the research paper entitled "Disordered Gd₆UO_12-δ with the cation antisite defects prepared by a combined mechanochemical-thermal method"[1]. The datasets complement the findings [1] on the effect of the combined mechanochemical-thermal processing of the stoichiometric mixture of solid precursors (3Gd₂O₃ + UO₂) on the formation of Gd₆UO_12-δ phase. In this article, we provide (i) X-ray diffraction (XRD) data of the 3Gd₂O₃ + UO₂ mixture milled for 12 h, (ii) the refined XRD data of the non-milled 3Gd₂O₃ + UO₂ mixture after annealing at 1282 °C for 3 h in air, and (iii) the thermogravimetric and differential thermal analysis (TG-DTA) data for non-milled and mechanically preactivated 3Gd₂O₃ + UO₂ mixture measured in air at a heat rate of 10 K/min.
