Bi-2212 coatings have been partially melted in a vertical (i.e., the plane of the coating is parallel to the force of gravity) and a horizontal setting. The vertical setting allows the partially melted grains to flow and on resolidification, form well connected grains that show a better performance in an applied magnetic field than coatings partially melted in a horizontal setting. The results presented here show that the vertical setting is better suited for magnet coil fabrication.
