Direct Synthesis of Cubic ZrMo_2O_8 Followed by Ultrafast In Situ Powder Diffraction

摘要

There has been a considerable amount of interest in negative thermal expansion (NTE) phases which are of importance, for example, in the manufacture of low or zero expansion composite materials. The cubic AM_2O_8 family of materials are of particular interest as the magnitude and isotropic nature of the NTE give them great technological potential. The exemplar material, cubic ZrW_2O_8, has been widely studied and can be prepared by a variety of methods including high temperature synthesis from the component oxides at 1473 K followed by rapid quenching.
