Low Members of the Intergrowth Tungsten Bronze Family by Partial Substitution of Molybdenum for Tungsten

Potassium and cesium intergrowth tungsten bronzes AxMoyW1−yO3 with x≲0.25 and y≲0.65 have been prepared. By substitution of molybdenum for tungsten the synthesis temperature can be decreased to 600°C and new phases of the structure family prepared. The ITB members designated (1, 3) and (1, 1, 3) hav...

Description
Summary:Potassium and cesium intergrowth tungsten bronzes AxMoyW1−yO3 with x≲0.25 and y≲0.65 have been prepared. By substitution of molybdenum for tungsten the synthesis temperature can be decreased to 600°C and new phases of the structure family prepared. The ITB members designated (1, 3) and (1, 1, 3) have been prepared in relatively phase-pure form, while individual crystals of (1, 2) and (1, 1, 2) have been identified by electron microscopy. These four phases have not been found previously in the ITB bronze systems.
