摘要
本文综述了近年来 γ- Fe2 O3超微粉在制备方法上的新进展 .作为气敏材料时 。
The new research progress in recent years to the preparation of γ-Fe_sO_3 ul trafine powders is summarized in this article. The mechanism of improve gas-sen sing properties and increase the temperature of phase transition by different ch emical compounds doped are described as gas-sensing materials.
