Reactions of tellurium oxides with alkali-metal oxides and hydroxides

Abstract

The double oxides Na₂TeO₄, K₂TeO₄, K₂TeO₃, and the triple oxides Na₄Te₂O₇ and K₄Te₂O₇ have been prepared by solid-state reactions of TeO₃ and TeO₃·H₂O with M₂O and M [OH](M = Na or K) and have been characterised by their X-ray diffraction patterns. The transformations and structures of the products obtained are discussed.
