摘　　要：以白云石为为原料,通过硫酸铵法实现了钙镁分离,加入改性剂水热处理后得到了平均粒径为40 nm左右的纳米氧化镁产品,研究了改性剂、水热处理对氧化镁形貌、粒径的影响。通过红外光谱仪、X射线衍射、扫描电镜对样品形貌及结构进行了表征。In the research dolomite was chosen as raw materials, ammonium sulfate method were used to extract the calcium magnesium compound from it. Finally got the average particle size of about 40 nm nano powder products after adding modifier and hydrothermal treatment. Modifier and hydrothermal treatment’s influence on the morphology and particle size of nanometer MgO was studied. The molecular structure and morphology were characterized using Fourier Transform infrared spectroscopy（FT-IR）, scanning electron microscope（SEM） and Xray diffractometer（XRD）.
