摘要

Abstract

Uniform pseudocube nano-iron oxide red (hematite)particles was prepared in the liquid phase by using δ-FeOOH as seed and iron as raw material at low temperature. The effects of such factors as initial pH of reaction

concentration of catalyst

reaction time on the preparation of these hematite particles were investigated. The product was characterized by XRD

FESEM. The results showed that pure pseudocube hematite particles could be prepared under the experimental conditions of solution initial pH 7

β=0.09（β=［Fe2+］/［δ-FeOOH］）

air oxidation temperature and time of 100℃ and 48 h respectively. The product crystallized integrally with particle diameter 90—100 nm

and its color was brightly red. This is a new method to prepare high-purity nano-iron oxide red with the characteristics of simple operation

non-pollution and low cost.
