中文摘要：
研究以硫酸钪（Sc2（SO4）3）和六次甲基四胺（（CH2）6N4）为原料，通过向Sc2（SO4）3溶液中滴加（CH2）6N4溶液，制备出了前驱沉淀物，该前驱沉淀物的化学组成为Sc（OH）2.2（SO4）0.4·0．4H2O，并分析了前驱沉淀物的热分解行为。前驱沉淀物经1100℃煅烧4h后得到了平均粒径为80nm、分散性良好的超细粉体。
英文摘要：
Synthesis of the precursor precipitates from scandium sulfate and hexamethylenetetramine[ （CH2）6 N4] using a homogenous precipitation method was investigated. Chemical composition of the precursor precipitates is （Sc（OH）2.2（SO4）0.4）·0.4H2O. Phase transformation of the precursor precipitates during calcinations was investigated by X-ray diffractometry. A Sc2O3 nanopowder with good dispersion and a mean particle size of 80nm was obtained by calcining the sulfate precursor at 1100℃ for 4h.
