This paper describes synthetic routes to produce highly O-17 enriched samples of the negative thermal expansion materials ZrW2O8 and ZrMo2O8. In the case of ZrW2O8 enriched samples can be produced either via enriched Zr-17 O-2 and (WO3)-O-17, which have themselves been characterised by both X-ray diffraction and solid state O-17 NMR, or via the hydrated material ZrW2O8-xH(2) O-17. In the case of ZrMo2O8 energy dispersive in-situ diffraction experiments have shown that cubic ZrMo2O8 can be directly hydrated to form an enriched sample of ZrMo2O7(OH)(2)-2H2O which can subsequently be transformed back to enriched cubic ZrMo2O8. O-17 NMR data of enriched ZrW2O8 materials are reported. (c) 2005 Elsevier SAS. All rights reserved.
