Intergrowth tungsten bronzes

Fig. 2.94 Structure model deduced from Fig. 2.93. The arrows I show the rows of tunnels of hexagonal prisms. The structure can be regarded as the intergrowth of HTB and DRO, which was named intergrowth tungsten bronze (1TB) by Kihlborg and co-workers.

Fig. 11. Schematic drawing of (1,4), (1,5) and (1,6) intergrowth tungsten bronzes. Hexagonal tunnels of HTB strips separate the W03 slabs shown in polyhedral form (after Kihlborg [92]).

Figure 31 (a) Electron micrograph of a crystal of an intergrowth tungsten bronze phase in the K.WOa system. The structure consists of slabs of WOs-like structure five octahedra wide separated by strips of the hexagonal tungsten bronze type, (b) A drawing of the idealized structure of the crystal in (a)... 

Intergrowth tungsten bronzes exist when hexagonal tungsten bronzes coherently intergrow with the parent WO3 stmcture (Figs. 4.14 and 4.15).
