Abstract
PURPOSE:To obtain the titled superconducting material having high critical temperature, large critical current density and narrow transition temperature range, by mixing alkoxides of prescribed three kind of elements consisting of Mg, Y and Cu, etc., in a solvent, adding an acid thereto to dissolve the mixture, adjusting pH with amines, etc., hydrolyzing the solution and calcining the resultant production mixture. CONSTITUTION:Alkoxides of (A) one or more kind of elements selected from Mg, Ca, Sr and Ba, (B) one or more kinds of elements selected from Sc, Y and lanthanoids and (C) Cu are mixed at a prescribed ratio (e.g. metal atomic ratio of alkoxide of A element/Y alkoxide/Cu alkoxide = 2-10/1/3-10) in a solvent (e.g. methanol) and an acid (e.g. acetic acid) is added thereto so as to pH: 2-5 to dissolve the mixture. One or more kind of compounds selected from amines, NH3 and amino alcohol are added to the solution not so as to exceed pH: 10 to hydrolyze the solution and the hydrolyzed production mixture is cleaned and then calcined at 800-1,000 deg.C for >=2hr to provide the aimed oxide-based superconducting material.
