摘要
采用NaH2 PO4 作为矿化剂,将FeCl3在2 0 0～2 2 0℃下水热反应4h ,得到了一种新型的单分散哑铃形αFe2 O3粒子,并发现H2 PO4- 和Fe3+ 的起始浓度、水热温度显著影响水热产物的形状和结构.
A novel type of mono-dispersed dumbbell-shaped α-Fe_2O_3 particles was prepared through the hydrothermal reaction of FeCl_3 at 200～220?℃ for 4?h with NaH_2PO_4 as a mineralizing agent. It's found that the initiative concentrations of H_2PO_4- and Fe 3+ as well as hydrothermal temperature affect the shape and structure of the hydrothermal products remarkably.
