Synthesis of nanocrystalline rare earth oxides by glycothermal method

摘要: Abstract The reaction of yttrium acetate hydrate in 1,2-propanediol at 300 °C yielded a product containing groups and glycol moieties. From this product, Y 2 O 3 was directly crystallized 400 °C without the formation carbonate oxide phase. thus-obtained samples had small crystallite size (2.2 nm) significantly large surface area (280 m /g). Other nanocrystalline rare earth (Gd–Yb) oxides were also obtained by method.
