Abstract
A study of the thermal decomposition of Cu x Co 2- x (OH) 3NO 3 solid solutions, 0.0 ⩽ x ⩽ 2.0, was performed by differential thermal analysis, thermogravimetric analysis and differential scanning calorimetry under non-isothermal conditions. It was found that the onset temperature, the endothermic peak temperature and the enthalpy of decomposition increase non-linearly with x. Kinetic analysis of the thermal decomposition was also made by the Flynn and Wall, Kissinger and Takhor methods. The values of the activation energy determined by the three methods are very close and also indicate non-linear dependence of the thermal stability on composition. It is suggested that the behaviour of the investigated thermodynamic and kinetic parameters is related to the variation of the strength of the hydrogen bonds in the structure and the polarisation ability of the cations.
