以稀土氯化物溶液为原料，碳酸氢铵为沉淀剂，在微波和超声波协同作用及常规加热条件下制备氧化铈超细粉体，考察了超声波功率和陈化时间对氧化铈粉体粒度的影响。试验结果表明：与常规加热相比，单一微波加热及协同加热模式下制备的氧化铈形貌更规则，粒径更均匀、更细，分散性更好，控制较短的陈化时间可得到平均粒径在0．2μm左右的超细氧化铈。
以稀土氯化物溶液為原料，碳痠氫銨為沉澱劑，在微波和超聲波協同作用及常規加熱條件下製備氧化鈰超細粉體，攷察瞭超聲波功率和陳化時間對氧化鈰粉體粒度的影響。試驗結果錶明：與常規加熱相比，單一微波加熱及協同加熱模式下製備的氧化鈰形貌更規則，粒徑更均勻、更細，分散性更好，控製較短的陳化時間可得到平均粒徑在0．2μm左右的超細氧化鈰。
