초록

High Tc Y-Ba-Cu-O Superconductors were fabricated by sintering, sintering + HIP and Hot Pressing. Specimens were sintered at $940^{\circ}C$ and $960^{\circ}C$. In case that sintered specimens were treated by HIP, the relative density was increased 5-6% in comparison with sintered ones. X-ray analysis of each specimens represented orthorhombic phase and Tc measurements showed a sharp drop in the temperature range $95-88^{\circ}K$. The relative density of hot pressed samples was lower than 80%.
