Anisotropies in both critical current carrying capacity and in fluxoid pinning from single‐crystal high temperature superconductors determine optimum orientations for directionally solidified (from the partial melt) microcrystals in material for coil applications. Optimization depends partly on the selected coil diameter. In melt texturing, crystal growth is accompanied by liquid flow which generally leads to the production of second phases by segregational effects except where careful procedures are adopted to prevent these. These segregational effects tend to reduce potential current carrying capacities even though they can in principle be used to increase flux pinning. Texturing of coils imposes special difficulties because of the mechanical weakness of the partially melted region. Process in overcoming these difficulties is of great importance to a significant range of applications requiring either higher magnetic fields than are attainable with conventional superconductors or the economy of superconduction at higher temperatures.
