摘　　要：以八水氯氧化锆和草酸钠为原料,固相反应合成出前驱体二水草酸氧锆,前驱体在600℃分解5 h,得到氧化锆粉体。结果表明,产物为粒度分布均匀、纯度高、单斜相和四方相共存的纳米氧化锆粉体,其一次颗粒尺寸在15 nm左右。Precursor ZrOC2O4-2HaO is synthesised by solid state reaction of ZrOCI2-8H2O with Na2C.204. Zirconia powder is obtained by decomposing of the precursor at 600℃ for 5 h. The results show that the product is nanometer zirconia powder including monoclinic phase and tetragonal phase, the distribution of particle is spherical, the powders is high purity and have a mean diameter of about 15 nm.
