Y_2O_3 nanopowder is synthesized directly from YCl_3 solution of industry with precipitation through making supermicro-reactant by non-surfactant and the purity and particle diameter of Y_2O_3 nanopowder are controlled by the process.

• 直接采用工业中间体YCl3为原料,以非离子表面活性剂配制超微反应器,碳酸钠为沉淀剂合成得到纯度、粒度可控的单分散纳米Y2O3微粒。
