Popis:	Submicrometre (La-3137) superconducting powder is prepared by a polymeric polyprotic acid (PA)/ethylene glycol (EG) derived precursor method. Six different PAs, oxalic acid, succinic acid, adipic acid, malic aid, tartaric acid and citric acid, are selected. It is found that of the six PAs citric acid gives the best results in terms of the particle size, homogeneity, carbon residue and values of the resulting La-3137 superconducting powder.
