Abstract :
This technology allows one to produce long HTSC coatings for manufacture of tapes and wires, shields and antennas. Gas-thermal methods allow one to obtain films (10-100 /spl mu/m) on non-oriented substrates of arbitrary shape. Crystallisation produced by the gas-flame method allows one to obtain dense coatings with high adhesion. These HTSC composites are easy workable to shape into the desired geometry. Parameters for Bi-Sr-Ca-Cu-O are T/sub c/=107 K, j/sub c/=2 10/sup 3/A/cm/sup 2/ at T=77 K. The proposed method has high productivity and low cost.<>
