Synthesis and thermal properties of Co2P2O7 · 6H2O

Abstract

The dependence of solid phase composition on the main parameters of the interaction in the CoSO4-K4P2O7-H2O system was studied. The synthesis conditions were determined and a crystalline cobalt(II) diphosphat of the composition Co2P2O7 · 6H2O was synthesized. Its thermal properties were studied. The composition and the intervals, wherein the thermally stable products of partial and complete dehydration of Co2P2O7 · 6H2O are formed, were specified. The final heat treatment product, anhydrous α-Co2P2O7, was identified and a sequence of the solid phase thermal transformations accompanying its formation was established.
