摘 要：<正>he complex oxide Dy10W2O21 was synthesized by a solid-state reaction and isolated in cubic symmetry by an X-ray diffractometry （XRD） method. Differential scanning calorimetry （DSC） measurements show that the compound is thermodynamically stable. The intrinsic thermal expansion coefficients were determined by extra-power powder X-ray diffractometry from room temperature to 1 000℃: linear coefficient a = 1.07 × 10-5 ℃-1 and bulk coefficient β= 3.20 × 10-5 ℃-1. Dilatometry was used to measure the extrinsic thermal expansion coefficient （9.2×10-6℃-1）.
