对纳米级CexZr1-xO2固溶体的制备方法进行了综述。其中共沉淀法工艺简单,所得固溶体粒度均匀,便于工业化生产;水热法所得产物粒度均匀,平均粒径可小于10nm;中低温固相反应法无需溶液,是一种“绿色化学”新工艺。
The preparation methods of nanocrystalline CexZr1-xO2 solid solution were reviewed. The method of coprecipitation method is simple, and the obtained solid solution has uniform particle size, which is convenient for industrialized production. The hydrothermal method has a uniform particle size and an average particle diameter of less than 10 nm. The low-temperature solid-phase reaction method requires no solution and is a new technology of “green chemistry”.
