 note = {High Tc Y-Ba-Cu-O superconductors were prepared by conventional sintering and annealing technique from calcined pellets which formed under pressure of 1, 2, 3, 4 ton/cm^2. It is found that the critical temperatures Tc of the specimens sintered in air are independent on the forming pressure but dependent on the lattice constant c. The lattice constants a and b are very stable under any preparated condition. And it is found by micrograph observation that the YBa_2Cu_3O_<7-x> specimen include many piller shaped single crystals is the high Tc (> 90 K) superconductor. Discussions are also given for the annealing treatment to the poor superconducting samples., 紀要論文},
