Structure and Thermal Expansion Behavior of Dy2-xGdxMo4O15 Solid Solution

摘要：

　　A new series of solid solutions Dy2-xGdxMo4O15 (x =0.0-0.9) were prepared.These compounds all crystallize in monoclinic structure with space group P21/c.The lattice parameters a,b,c and unit cell volumes V increase almost linearly with increasing gadolinium content.The intrinsic thermal expansion coefficients of Dy2-xGdxMo4O15 (x =0.0 and 0.25) were obtained in the temperature range of 25 to 500℃ with high-temperature X-ray diffraction.The correlation between thermal expansion and crystal structure was discussed.
