摘　　要：称取4.83gAlCl3·6H2O与5.30gNa2CO3粉末于研钵中,在室温下充分混合研磨反应40min得到反应混合物,用蒸馏水洗去其中的可溶性无机盐后烘干,即可得到产物粉末。采用XRD与TEM对产物粉末进行表征,结果表明,所合成的产物为碱式碳酸钠铝,其一次粒子的平均粒径约80nm,收率为96%。At room temperature, the precursor mixture was obtained when 4.83 g AlCl_3·6H_2O and 5.30 g Na_2CO_3 were grinded and reacted 40 min thoroughly. The soluble inorganic salt was removed by washing with water. After drying, the product is obtained. The product is characterized by XRD and TEM. The results showed that the product is basic sodium aluminum carbonate, and the average particle size of the basic sodium and aluminum carbonate powder is about 80 nm, and the yield is up to 96%.
