Preparation of nano‐MgO by ionic liquid‐assisted solid‐state reaction

Nanocrystalline MgO particles with a cubic phase structure have been synthesised via ionic liquid (IL)‐assisted solid‐state reaction. The necessary characterisations such as XRD, EDS, FTIR, SEM and TEM have been carried out to investigate the obtained materials. The results show that the synthesised MgO consisted of a large quantity of sphere‐like nanocrystals with average particle size of ∼26.3 nm, and had high crystallinity and narrow particle size distribution. Compared with solid‐state reaction method, this method has the advantages of fast reaction rate and high yield. This indicates that IL‐assisted solid‐state reaction appears to be a promising method for the manufacture of nanometre MgO in industry.
