摘　　要：以氧化锌和硼酸为原料通过溶剂热改性法制备了亚微米级低水硼酸锌（2ZnO·3B2O3·3H2O），利用化学分析、XRD、SEM和IR等手段对产物进行了表征。结果表明：溶剂热改性法可以制得团聚少，分散性好，结晶程度高，粒径0．2-0．4μm的亚微米级低水硼酸锌（2ZnO·3B2O3·3H2O）颗粒；TC分析表明，合成样品的开始脱水温度在290℃左右。并对反应机理进行了简单探讨。A Submicron 2ZnO·3B2O3·3H2O powder was prepared by solvothermal treatment route using ZnO and H3 BO3 as raw materials ,and studied by chemical analysis ,XRD, SEM and IR. The results showed that the products were uniformly sized submicron （0.2 - 0.4 μm） with low aggregation, fine crystallization and superior dispersing ability. The initial dehydration temperature of the sample analysed by TG was about 290 ℃. The mechanism of the reaction was also discussed.
