【Abstract】 La_2-xM_xCuO₄（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 un-successful.A brief discussion for applicability of the alkali flux method has been given.更多还原
