摘要
通过将反相微乳法与水热法相结合 ,制备出了纯度高、粒径均匀的Fe3O4 纳米粉。该方法克服了微乳法制样纯度不高和水热法制样晶粒尺寸难以控制的缺点。通过调节微乳体系中水与表面活性剂的比例 。
Fe 3O 4 nano-crystal with high purity and even particle size was prepared by combining microemulsion and hydrothermal method. This method can conquer the disadvantages of poor-purity in the W/O microemulsion method and uncontrollable-particle-size in the hydrothermal method. In a degree, the particle size of Fe 3O 4 nano-crystal could be controlled through tuning the ratio between H 2O and the surfactant in the microemulsion.
