摘　　要：采用固相法合成了纯度较高的Mg(OH)2,并利用XRD、SEM等进行了表征。以硬脂酸钠、油酸对其进行表面处理得到改性Mg(OH)2,沉降实验表明其与液体石蜡中有较好的相容性,而且油酸改性Mg(OH)2显示出更好的效果。Magnesium hydroxide powder with higher purity was prepared by solid phase method.The powder samples were characterized by XRD and SEM.The surface of magnesium hydroxide powder was treated by sodium stearic acid and oleic acid.The sedimentation experiments indicated that modified Mg（OH）2 samples had good compatibility with liquid paraffin and the modified Mg（OH）2 powders by oleic acid possessed better effect.
