Abstract
The preparation of Fe3O4 nanoparticle by liquid -phase coprecipitation was introduced. And the orthogonal experiment was designed. The optimized condition that the proportion of Fe3+/Fe2+ was 1:2, crystallization temperature of Fe3O4 nanoparticle was 90°C and crystallization time of Fe3O4 nanoparticle was 45min was achieved. Under the condition, the average size of nanoparticle is 10 nm to 20 nm. And BP nerve network is used to analyze the influence factors of the size of Fe3O4 nanoparticle such as proportion of Fe3+/Fe2+, crystallization temperature of Fe3O4 nanoparticle and crystallization time of Fe3O4 nanoparticle.
