X-ray diffraction and thermoanalytical datasets of precursors of the Gd${}_6$UO${}_{12-\delta }$ phase processed by combined mechanochemical−thermal routes

The datasets presented here are related to the research paper entitled “Disordered Gd${}_6$UO${}_{12-\delta }$ with the cation antisite defects prepared by a combined mechanochemical−thermal method”. The datasets complement the findings on the effect of the combined mechanochemical−thermal processing of the stoichiometric mixture of solid precursors (3Gd${}_2$O${}_3$ + UO${}_2$) on the formation of Gd${}_6$UO${}_{12-\delta }$ phase. In this article, we provide (i) X-ray diffraction (XRD) data of the 3Gd${}_2$O${}_3$ + UO${}_2$ mixture milled for 12 h, (ii) the refined XRD data of the non-milled 3Gd${}_2$O${}_3$ + UO${}_2$ 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 3Gd${}_2$O${}_3$ + UO${}_2$ mixture measured in air at a heat rate of 10 K/min.
