Highly textured ([ital c] axis perpendicular to the plane of the substrate tape) thick films of YBa[sub 2]Cu[sub 3]O[sub 7] grown on Ag[sub 0.9]Pd[sub 0.1] and pure silver substrates have been made by a traveling heated zone method. The speed of the traveling zone can be as fast as [similar to]5 cm/h and the temperatures of the zone, 930--975 [degree]C, were well below the peritectic temperature of YBa[sub 2]Cu[sub 3]O[sub 7]. A precursor layer, which consisted of a nitrate solution of yttrium, barium, and copper cations, was deposited by spray pyrolysis directly onto a heated substrate. The values of the resistively measured [ital T][sub [ital c]] were 83--91 K. The transport critical current density of these thick films was in the range of 2--8[times]10[sup 3] A/cm[sup 2] at 77 K and 0 T.
