Study of thermal properties of potassium μ-hydroxo-bis(oxo-diperoxovanadate)(V)

The thermal decomposition of K3[OH{VO(O2)2}2]·H2O was studied under dynamic conditions up to 350°C and also isothermally at 150°±3°C in self-generated atmosphere. K4[V2O6(O2)] is formed as the reaction intermediate. The final products of thermal decomposition of K3[OH{VO(O2)2}2]·H2O are KVO3 and K4V2O7.
