Kopsavilkums

We have done comparative XAFS analysis on the Mo K and W L₃ edges of polycrystalline Mo_xW_1-xO₃ solid solutions. It was found that their structures are closely related to corner-shared WO₃-type for x < 0.9 while α-MoO₃-type structure is present for x ≥ 0.9. The obtained structural parameters for the first shell around metal ions allow to distinguish several structural phase transitions due to the change of composition. A set of subshells within the first shell was found, and they are in good agreement with Raman data.
