The ammonium tungsten bronze has been prepared by soft-chemical synthesis method at ambient pressure. The hexagonal or cubic pyrochlore structure could be obtained from the same acidified tungsten system, depending upon the dissolution or not of the ammonium tungstate in the solvent before acidification...
