Y:123; [Y-Ba-Cu-O]
Material Specification for Y:123; [Y-Ba-Cu-O] Process: Solid State Reaction
Notes: "Phase-pure orthorhombic YBa2Cu3O7-x powder was synthesized by a solid-state reaction procedure during which the ratio of O2 to CO2 was kept higher than 50. This powder was cold-pressed into pellets which were sintered in O2 at 980 °C for 3 h. The heating and cooling rates were 3 °C/min, but to obtain high-density material no postsinter oxygenation annealing was employed so that the specimens contain some tetragonal phase at room temperature. ... Microstructural examination revealed the material to have a fairly uniform distribution of small grains of size less than about 30 µm."

"Pellets were polished lightly to give flat and parallel faces to about 10-4 rad. Ultrasonic pulses were propagated along the direction of pressing were generated by X- or Y-cut (for longitudinal and shear waves, respectitvely) quartz transducers bonded to the specimen using Nonaq in the low-temperature experiments. Measurements of the temperature dependence of the ultraonic wave velocity were made in a closed-crycle refrigerator in the temperature range 10-300 K. The temperature was changed at a rate about 0.5 K/min during both cooling and warming cycles. Dow resin was used as the bonding material for the high-pressure experiments, which were made in the range 250-295 K. Hydrostatic pressures up to 0.15 GPa were applied to the samples using a piston-and-cylinder apparatus with silicone oil as the pressure transmitting medium. Pressure was measured using a precalibrated manganin resistance gauge. To determine the effects of temperature and pressure on the ultrasonic wave transit time, a pulse-echo overlap system capable of measuring changes to 1 part in 10-5 in ultrasonic transit time in these ceramic specimens was used. A transducer correction was applied to the measured transit time and hence to the ultrasonic wave velocities."
