Abstract (en)
[origin: WO03091475A1] The invention relates to a method of preparing thick films of YBa2Cu3O7-y (y = 0.08) having a critical current density of the order of 10<6> A/cm<2>. The inventive method consists in using an inert carrier gas to send an aerosol, obtained from an aqueous solution of precursors of yttrium nitrate, barium nitrate and copper nitrate (0.11=FY=0.28, 0.46=FBa=0.58, 0.2=FCu=0.37,) having a concentration which is essentially equal to the concentration at saturation, to the surface of a heated substrate whereon it undergoes pyrolysis for between 1 and 5 mn at 800 DEG C and 870 DEG C, followed by oxygen annealing at a temperature which is greater than the pyrolysis temperature by at least 10 DEG C and between 850 DEG C and 880 DEG C for between 1 and 2 hours, and subsequently at 450 DEG C - 550 DEG C for between 0.5 and 1.5 hours.
