碳酸

The thermodecomposition of Li〓CO〓 charge was experimented and studied in a specially made vacuum furnace. The relationship of decomposition rate with temperature, pressure and time were obtained. The important principle of decomposition rate effected by pressure was acquired and conception of critical decomposition-pressure was presented.
