摘要: Abstract This paper presents experimental results on weakly magnetic field-assisted synthesis of magnetite (Fe 3 O 4 ) nano-particles in an oxidative co-precipitation method, comparison to the case without induction. The XRD show that a induction below 220 Gs could accelerate phase transformation from goethite (α-FeOOH) ), and affect crystal structure, particle size/morphology response synthesized. In addition, higher concentration FeCl 2 solution reaction led finer particles, both with
