以废催化裂化平衡剂为主要原料，配以滑石粉、工业氧化铝或石英，通过高温固相反应进行合成堇青石的实验，采用XRD和SEM等手段对合成产物进行表征。考察原料配比、焙烧温度和焙烧时间对合成堇青石的影响。实验结果表明，适当提高原料中铝、镁的含量，降低硅含量，可合成出高堇青石晶相含量的堇青石；合成堇青石较佳的条件为：原料配比废平衡剂61.42%（w）、滑石粉37.68%（w）、工业氧化铝0.90%（w），焙烧温度1200℃，焙烧时间2 h；在较佳条件下合成的堇青石，其堇青石晶相含量可达95%（w），形貌呈板（片）状。

The preparation of cordierite from spent fluid catalytic cracking(FCC) equilibrium catalyst,talc,industrial alumina and quartz through solid-state reaction was studied. The crystal phases and microstructure of the prepared samples were characterized by means of XRD and SEM. The results showed that the products with high content of cordierite crystal phase could be obtained from the raw materials with high contents of aluminium and magnesium and low content of silicon. A cordierite product with 95%(w) cordierite content could be prepared under the optimal conditions of the spent FCC equilibrium catalyst 61.42%(w),talc 37.68%(w),industrial alumina 0.90%(w), calcination temperature 1 200℃ and calcination time 2 h.
