摘 要: 通過(guò)對(duì)燒結(jié)后含鋰鹽炭陽(yáng)極糊的紅外光譜、X 射線(xiàn)衍射和熱分析研究表明，在鋁電解的溫度和條件下，炭陽(yáng)極中的Li2CO3僅少量分解且仍是其主要存在形式。由于碳的存在使Li2CO3的分解率大大降低，使其分解溫度大大高于文獻(xiàn)報(bào)道的Li2CO3的熱分解溫度。

Abstract:The samples of baked anodic paste adding Li2CO3 were studied by infrared and X-ray diffraction. It was shown that Li2CO3 in the baked anode is decomposed slightly in the condition of aluminum electrolysis in Soderberg cell. But the major form of lithium is still Li2CO3. Due to the existence of carbon, the decomposition of Li2CO3 is decreased greatly.
Key words: Li2CO3; thermal decomposition; aluminum electrolysis; anode
