| Abstract: | Barium hexaaluminate nanoparticles were prepared by reverse microemulsion.Compared with the method of gel-network-coprecipitation,the effects of washes,calcined temperature and reaction time were analyzed in the process of reverse microemulsion composition.The grain shape were studied by the composition conditions.The grain shape was controlled by the ratio between solution phase and oil phase.As the ratio is less,the grain shape is sphericity.When the ratio is incressed,the grain shape is claviform.The calcined temperature of reverse microemulsion is lower than the calcined temperature of gel-networkcoprecipitation. |
