Abstract

Abstract: FeCl₂ as the precursor, γ-FeOOH was prepared and the process conditions such as reaction temperature, reactants' concentration, NaOH dropping style were deeply investigated. Optimum condition was then concluded. The results indicated that during the crystal seeds' synthesis, temperature and reactants' proportion could influence the crystal seeds' morphology. During the growing process, the dispersion of NaOH in the system was depended both on the macro-mixing and micro mixing, especially the micro mixing.

Key words: γ-FeOOH, Synthesis, Ultrafine powder
