Abstract:Using MgCl2 and CO(NH2)2 as raw materials,the nanometer-sized MgO were prepared by homogeneous precipitation method.The influences of reaction temperature and time,raw materials ratio,and calcination temperature and time on product yield and particle size were investigated.The most favorable technological conditions for the preparation of nanometer-sized MgO were obtained.TG,XRD and TEM were used to characterized the sample.The product has an average diameter of 30nm with good dispersity and sphere-shaped.
Keywords:homogeneous precipitation method  nanometer-sized materials  MgO
