WebUnder argon decomposition commenced at 710–715 °C, but CO 2 was detected just above melting at 405 °C. In air, decomposition began earlier at about 600 °C, but CO 2 was evolved at 530–566 °C, probably due to the reduction of oxygen from the air driving reaction (3) towards the carbonate ion, suppressing CO 2 production relative to the ...
