| 英文摘要 | A new series of rare earth compounds, y2-xerxmo4o15 (x = 0.0-2.0), were synthesized and their structures were determined by powder x-ray diffracfion (xrd). rietveld analysis of xrd patterns reveals that the compounds of this series crystallize in monoclinic system with space group p2(1)/c. the lattice parameters a, b, c, beta and the unit cell volume v decrease linearly with increasing er content. the thermal expansion properties of these compounds were studied under high-temperature xrd. positive thermal expansions of compounds y2-xerxmo4o15 are found to be anisotropic along the three crystallographic directions where a and c axes expand while b axis contracts in the whole temperature range. by analysis of data, the expansion of weak band mo2-o14 with rising temperature should be responsible for positive thermal expansion. |
