A partial melt/texture growth process has been applied to plasma-sprayed YBa{sub 2}Cu{sub 3}O{sub 7{minus}{ital x}} deposits. The length of the aligned grains is in the range 300--500 {mu}m. Small-angle grain boundaries with a misorientation between 3{degree} and 5{degree} are commonly observed. The critical current density, using a four-probe method with continuous direct current, is in excess of 5000 A/cm{sup 2} under an applied field of 1 T at 77 K.
