摘 要: 通过对烧结后含锂盐炭阳极糊的红外光谱、X 射线衍射和热分析研究表明，在铝电解的温度和条件下，炭阳极中的Li2CO3仅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，使其分解温度大大高于文献报道的Li2CO3的热分解温度。

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
