Preparation of Nanocrystalline Y2O3 in Reverse Micelles and Microemulsions
Abstract:
Monodisperse nanocrystalline Y2O3 in size 30 um was prepared in "microreactors" of reverse micelles and microemulsions, formed from cetyltrimethyl ammonium bromide, butanol and Y(NO3)3 in cyclohexane.The mechanism of the crystalline formation has been discussed based on the results of TG-DTA, XRD and TEM measurements.The addition of butanol showed a great influence on the stability of the microreactor membrane.The optimum content of butanol was found.The size of Y2O3 depended on the calcination temperature: the higher the temperature, the larger the nanocrystalline.
