Preparation and properties of Y‐124 superconductor made by a chemical precipitation method

We have prepared the thermodynamically stable YBCO‐124 high temperature superconductor in powder form by a chemical precipitation method and have characterized the material by a number of chemical and physical methods, including carbon content, x‐ray diffraction, thermogravimetry, scanning electron microscopy, surface area, thermally stimulated luminescence, and the superconducting transition and magnetization curves. We have also started work on consolidating the powders by hot pressing.
