Zusammenfassung:	PCT No. PCT/FR95/00059 Sec. 371 Date Jul. 23, 1996 Sec. 102(e) Date Jul. 23, 1996 PCT Filed Jan. 19, 1995 PCT Pub. No. WO95/20550 PCT Pub. Date Aug. 3, 1995The present invention relates to method of preparing a superconductor material consisting in preparing a precursor constituted by a powder of Ba2Can-1Cun+1Ox or Ba2Can-1Cun+1Ox where n is an integer greater than 1 and x is greater than 2n+2; in mixing said powder with silver oxide power, optionally in the presence of excess copper oxide, in a proportion of one mole of precursor for one to three moles of silver oxide; and in heating to high temperature and high pressure.
