采用微波加热法制备了分布极窄的超细α-Fe 2 O3纳米粒子。颗粒的平均直径为约7 nm。这些纳米颗粒在胶体状态下非常稳定，即使在不存在稳定剂的情况下也是如此。所得α-Fe 2 O3纳米粒子可作为可充电电极材料.初始放电容量超过400 mA hg-1（截止电压：1.0V）。
Ultrafine α-Fe 2 Ο 3 nanoparticles with an extremely narrow distribution were prepared by microwave heating. The average diameter of the particles was approximately 7 nm. These nanoparticles were extremely stable in the colloidal state, even in the absence of stabilizers. The obtained α-Fe 2 O 3 nanoparticles worked as a rechargeable electrode material. An initial discharge capacity exceeded 400mA hg -1 (cut-off voltage: 1.0V).
