摘要
本文以InCl_3为铟源,采用溶剂热方法先制得In(OH)_3微米块。再把In(OH)_3微米块置于管式炉中500℃煅烧3 h得到了立方相的In_2O_3微米块,并研究了不同升温速率对In_2O_3微米材料形貌的影响,实验结果表明升温速率对In_2O_3的形貌有很大的影响,升温速率缓慢(2℃·min^(-1))有利于保持In_2O_3长方体的形貌,若升温速率过快(20℃·min^(-1)),会得到In_2O_3微米颗粒。
In（OH）3 microcuboids were prepared at 180 ℃ fbr 12 hours via a solvothermal route, using lnCI3 as the indium source. Then In203 micron block were obtained by calcining the In（OH）3 in the furnace at 500 ℃for 3 hours. The effect of heating rate on the ln203 micromaterials was studied. The experimental result indicated that the heating rate had a great influence on the morphology of lnzO3. The slow heating rate （2 ℃.minq） was beneficial to keep the morphology of lmO3; otherwise, In：O3 nanoparticles were obtained with a higher temperature elevation speed （20 ℃.min-1）.
