Abstract
Submicrometre La3CaBa3Cu7Oy (La-3137) superconducting powder is prepar ed by a polymeric polyprotic acid (PA)/ethylene glycol (EG) derived pr ecursor method. Six different PAs, oxalic acid, succinic acid, adipic acid, malic aid, tartaric acid and citric acid, are selected. It is fo und that of the six PAs citric acid gives the best results in terms of the particle size, homogeneity, carbon residue and T-c values of the resulting La-3137 superconducting powder.
