Abstract
The relationship between the substitution rate of Sr for Ba and the me lting point of REBaCuO-system superconductor was measured. Various cal cined powders of composition RE1.8(Ba1-xSrx)(2.4)Cu3.4Oy (for x = 0, 0 .125, 0.250 and 0.375; RE = Y, Sm and Nd) with 0.5 wt% Pt powder were prepared and the melting points were measured by differential thermal analysis (DTA).The melting points of the YBaCuO-system and the SmBaCuO -system for x = 0.375 were 29 degrees C and 56 degrees C higher than t hat of a non-substituted sample. The melting point of NdBaCuO-system w as observed to be almost unaffected by the substitution of Sr for Ba. (C) 1998 Elsevier Science S.A. All rights reserved.
