Preparation and characterization of magnesium oxide ultra -thin particles

Magnesium oxide ultra-thin particles were prepared by homogenous precipitation technique, using Mg(NO3)2 as the raw materials. The effect of some experimental conditions were discussed in detail, including the surfactant concentration, pH value and sintering time etc. The products were characterized by XRD, AFM, IR and DTA methods. The results indicate that the MgO crystallized in a cubic halite form with(200) and(220) preferential orientation. The mean particle size and the specific area are about 12nm and 78.02g·m-2 respectively.
