Thermal decomposition of basic copper carbonate, CuCO3 · Cu(OH)2 · H2O, in carbon dioxide atmosphere (0–50 atm)

The thermal decomposition of basic copper carbonate, CuCO3 · Cu(OH)2 · H2O, was studied by high-pressure DTA under high-pressure carbon dioxide (0–50 atm). The DTA-TG measurement in air showed that the peak temperature was influenced more by heating rate than by sample weight. Decomposition via dehydration and decarbonation was rapidly finished in a single step, and no intermediate was found. The decomposition temperature was strongly influenced...
