摘要：

The synthesis of alkali substituted lanthanum copper oxide La2-xMxCuO4 (M=Na, K, Rb, Cs) by the low temperature hydroxide melt technique is described. The alkali stoichiometry x turned out to be dependent upon the reaction temperature. Superconducting phases appear in the Na and K substituted compounds with a maximum T(c) of 31 and 41 K, respectively
