Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub x} tapes and wires were prepared by the powder-in-tube technique. In particular, the packing of the tube and the heat treatment were optimized to reduce the generation of bubbles and to obtain short samples with high critical current densities. The samples were tested in magnetic fields up to 20 T at 4.2 K. The microstructure of the samples was analyzed by a scanning electronic microscope and electron dispersive X-ray spectroscopy. Small monolayer coils were prepared by the wind-and-react technique to test the compatibility of different coil related materials to the Ag-clad conductor.
