| Abstract: | The preparation method of W/O microemulsion was studied.The maximum water content in W/O microemulsion under given conditions was found out. The mixed hydroxide of Mg(OH) 2 Fe(OH) 3 was prepared by precipitation method by means of using W/O microemulsion as microreactor.Finally,the nano spinel MgFe 2O 4 was prepared from the mixed hydroxide by solid phase reaction and crystallization at high temperature.The nano MgFe 2O 4 was characterized by XRD and TEM as well as colour measurement.The quantum size effect of nano particles was discussed. |
