摘要

用电弧等离子体火焰熔炼得到了La2O2·7Al2O3、Pr2O3·7Al2O3、Nd2·8Al2O3和Sm2O3·7Al2O3等近似分子式的新化合物，并经适当的化学处理分离成各自的单相。所有化合物均具有β-Al2O3型结构。除La2O3·7Al2O3外，这些化合物在温度高于1500℃时均具有β-Al2O3型结构。

Synthesis of Lanthanoid Aluminates (β-Al_2O_3 Type) Using Arc Plasma Flame

New compounds with approximate formulas, La2O2·7Al2O3, Pr2O3·7Al2O3, Nd2·8Al2O3 and Sm2O3·7Al2O3, have been obtained through melting by arc plasma flame and separated into their own single phases by a proper chemical treatment. All of the compounds have the β-Al2O3 type structure. Excepting only La2O3·7Al2O3, these compounds have the β-Al2O3, type structure at temperatures higher than 1500°C.
