Formation of anisotropic Tl-1212, Tl-2212, Tl-1223 and Tl-2223 particles using aerosol flow reacted powders


Highly anisotropic particles of Tl-1212, Tl-2212, Tl-1223 and T1-2223 superconductors were grown. The Tl-free precursor powders with the compositions Ba/sub 1/Ca/sub 2/Cu/sub 3/Ag/sub 0.37/O/sub 6/ and Ba/sub 2/Ca/sub 2/Cu/sub 3/Ag/sub 0.37/O/sub 7/ were prepared using an aerosol flow reactor. These precursor powders were then post-annealed in 0.1 atm… (More)
