摘要
称取5.75 g ZnSO4.7H2O和7.60g Na3PO4.12H2O粉末于研钵中,用微量进样器吸取60μL表面活性剂聚乙二醇辛基苯基醚(OP)与之混合均匀,在室温下充分混合研磨反应30 min,洗去其中的可溶性无机盐,在125℃烘干2 h后得到产物粉末。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Zn3(PO4)2.2H2O晶体,其粉末一次粒子的平均粒径约为70 nm,收率为95%。
At room temperature, the precursor mixture was obtained when 5.75 g Na3PO4·12H2O powder and 7. 60 g ZnSO4 · 7H2O powder with 60 μL surfactant OP were grinded 30 min thoroughly. Then soluble inorganic salts were removed by washing with water, and the product powder was obtained by the precursor at 125℃ for 2 h. The product was characterized by XRD and TEM. The results showed that the product was Zn3 （PO4）2· 2H2O crystal, and the average particle size of it was about 70 nm, and the yield rate was up to 95 %.
