Abstract

PURPOSE:To obtain a superconductor compsn. capable of providing a ceramic body at lower sintering temp. by completing decomposition of carbonates at a lower temp. by using a constituent consisting of a specified component contg. Sr, Nd, Cu, and O. CONSTITUTION:The title superconductor compsn. is an oxide superconductor compsn. expressed by the formula I wherein 0.3 <=x<=0.85. When the compsn. is sintered at 850-900 deg.C, a material having high density and high critical temp. is obtd. Although a conventional Ba-Y-Cu-O type compsn. provides a product having ca.80% relative density when it is precalcined at 900 deg.C for 12 hr then sintered at 1000 deg.C, the compsn. of the formula II provides a superior ceramic product having ca. 92 % relative density when it is precalcined at 850 deg.C for 12hr and sintered at 950 deg.C. The ceramic is confirmed to be a superconductor having high critical temp. by a measurement of resistance. The compsn. of this compsn. provides a dense ceramic having high critical temp. at a lower sintering temp. than conventional compsns., accordingly, the compsn. has higher practicality for superconducting material.
