Abstract: La2-xMxCuO4(M=Ca,Sr,Ba) superconductors have been synthesized at 280~300℃ by precipitation from molten NaOH/KOH/KNO3.However,synthesis of Tm-Ca-Cu-O,Sr-Ca-Cu-O and Hg-Ba-Ca-Cu-O superconductors by using the alkali flux method are unsuccessful.A brief discussion for applicability of the alkali flux method has been given.

Key words: high-Tc superconductor, alkali flux method, synthesis
