Abstract

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.

电弧等离子体火焰合成类镧铝酸盐(β-Al_2O_3型)

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。
