The electrical conductivities of pure and doped manganese(II) carbonate with 10 mol% Li+ or Al3+ ions were measured. The effect of doping on the observed kinetic parameters of decomposition were measured. Doping with Li+ or Al3+ ions enhances the decomposition. The enhanced promotion effect is ascribed to the generation of hole defects which are concentrated at the reaction interface.
