Preparation and structure of mixed tungsten bronzes containing tin and europium
- 1. Univ. of Bradford, Eng.
Description
An isothermal section has been established for the system Eu/sub x/WO3-Sn/sub y/WO3 at 10000C from X-ray powder and single-crystal data and Moessbauer spectroscopy and chemical analyses. A single-phase region with the (12 x 3) tetragonal structure has been established. Single-crystal X-ray analysis shows that the Sn and Eu occupy pentagonal tunnel sites. Moessbauer spectroscopy shows that both Sn(II) and Eu(II) are present. The extent of the single-phase field is controlled by two factors: First, the ratio Eu/Sn must be less than 1, and second, the supernumerary electron concentration per WO3 must be less than 0.6
