摘　　要：以草酸铵和氯化镁为主要原料,利用热分解和微波辅助煅烧草酸镁制备氧化镁粉体,研究了微波功率、微波辐射时间对草酸镁分解率的影响,并通过X射线衍射对制得的氧化镁粉体进行表征;结果表明微波辅助加热具有时间短,粉体结晶度好的优点。Methods of preparing MgO powder through microwave calcination and thermal decomposition of basic MgC2O4＋H20, which is prepared with （NH4）2C2O4＋ H20 and MgCI2. 6H2O as raw materials, are investigated in this paper. The effects of microwave power, radiation time on the rate of MgC2O4. H20 decomposing is researched. The products from experiments were characterized and analyzed by X-ray diffraction （XRD）. The results indicate that the microwave-assisted calcination time is short and the grain is fine compared with thermal decomposition.
