摘要：

To investigate effect of a technological scheme on the structure and superconducting parameters of powder composites YBaCuO-Ag, three types of pressing of powder mixtures were used, i.e. static, hot, and dynamic pressing. Silver content changed in the range c = 0-50 vol.%. Orthorombicity degree, b/a, of the YBaCuO-ceramics proved to be practically independent on c up to c = 30 vol.% for static and hot pressing, and it decreased appreciably even at small c values in the case of dynamically pressed samples, Critical temperature T-c and transport critical current density jc show similar behaviour with maximum about c = 10 vol.% for static and hot pressing, Dynamic pressing results in significant deterioration of these parameters.
