High critical current densities at the level of magnetic field needed for specific operation, is an important prerequisit for the application of all kinds of superconductors. The discovery of the high Tc superconductors created enormous new hopes for a much broader breakthrough for superconductivity

YBa2Cu307 crystals fabricated by a quench and melt growth process contain fine Y2BaCuO5 particles. These fine precipitates are considered to have three beneficial effects: they suppress crack formation; they promote oxygen diffusion; and they act as pinning centres. Such crystals exhibit larger flux

Y1Ba2Cu307\_x and Bi2Sr2CalCu208+ x Ag sheathed high Tc superconductor wires have been prepared using the powder in tube technique. Characterization of wire specimens was performed mainly by measuring critical current densities at 77 K and 4.2 K, as well as by a.c. susceptibility measurements. Where
